A guy follows some strange, green lights. He eventually finds someone, and asks if she can help him. He was following the light, but now he's lost. Morrigan appears, and says she is the light -she called him to her.

She says it has been far too long since she fed on the life energy of a strong young man. She tells the guy he is lost, and he's also her dinner. She kisses him and starts to take away his energy, but then a voice calls out to her. Morrigan sees another man standing on a rock, so she asks him who he is and what he wants.

Donovan Baine introduces himself, and says he's a master of sorcery. He says he wants nothing less than her complete destruction! He uses his sword to unleash an energy blast.

Morrigan flies off and asks if that's the best he can do. She fires back, so Donovan jumps up. He says he calls himself the dark hunter, and attacks again.

Morrigan uses her wings to defend herself. Donovan summons a spirit, which picks up his sword and uses it to throw out several projectiles. Morrigan does some acrobatics to avoid them.

She charges over to Donovan, and kicks him down. She tries to charge into him, but he leaps up and then floats in the air. Morrigan says this has gone on long enough, and Donovan says it has. He then summons an ice spirit, which throws out many icy projectiles. Morrigan tries to avoid them...

...but one of them hits her, and freezes her. Donovan lands, but before he can finish her off, she manages to shatter the ice and escape.

She uses her powers to move a massive block of ice, and push it towards Donovan. He starts hacking it to pieces, but by the time he's finished, Morrigan has gone. He says she can't have escaped, as his sword has tasted her aura. He tells his sword to find it again, and lead him to her. He says there will come a reckoning.

Meanwhile, Felicia and Harry are on a plane, which is flying to England. Felicia wants to see the ring again, so Harry displays it on his laptop. He says he came across it totally be accident, on a CD rom of all the ancient stuff in the British museum. It has just been identified as a silver and onyx ring, circa 5th century AD. Harry then pulls out a book, and says it was written by Elijah Grimoire -his great, great, great grandfather.

He shows Felicia a picture of the ring in the book, and says it was something his ancestor drew: the ring of the black dragon. Felicia says that's definitely the same ring, which means it rightfully belongs to Harry. Harry says the book states the ring is the key to enlightenment for any Grimoire who seeks the path of magic. Felicia says she hopes so, as he needs all the enlightenment he can get if he's going to control his powers. Harry wonders what his powers are, so far all he can do is float, and he can't even control that. Felicia says it beats her, as she's not the wizard around here.

Elsewhere, Morrigan enters a cave, and complains about Donovan. She's never heard of him before. A bat appears and talks to her in a language she can understand. The bat suggests calling Demitri, but Morrigan says she's not going to call him for help. If she did, he's get a good laugh at her expense that she had to run from a mere human sorcerer. The bat asks if she can beat Donovan, and Morrigan says of course she can -he just took her by surprise. She admits he was terribly powerful, so what she needs is a magical boost. The bat suggests something, and Morrigan says yes: the ring of blood. She'd been meaning to get it back ever since it showed up at the British museum. Once she has it, Donovan Baine is toast!

At the British museum, Felicia and Harry are looking around. Harry tells Felicia here it is, just like how Elijah drew it. He wants to find out whoever is in charge around here and tell them that it belongs to him. Felicia stops him and says they won't turn over an ancient artifact over to some American kid, they won't believe him. She says she'll get the ring for him, and she's seen all she needs to see for now. She suggests they go and find some fish and chips whilst they wait for the museum to close.

Meanwhile, Morrigan arrives in England. Later on, Harry and Felicia get to the roof of the building next to the museum. Harry's says he doesn't like this, as it's like stealing. Felicia asks how can you steal something that belongs to you? She tells him they're just retrieving it, so he can learn to use his powers.

Felicia then says that someone has put a concealment spell on the museum. It won't keep them out, but it will keep any humans that are around from detecting what's going on inside. It means that someone else is interested in the museum. Harry says he can't see anything, but Felicia tells him to try -he's a wizard, so he should be able to see the spell. Harry concentrates, and says he can see it.

In doing this, he suddenly starts floating. Felicia grabs him and asks what he's doing, and he says he can't help it. When he tried to see the spell, it kicked in his flying power, he can't control it. Felicia says they'll get inside fast, and takes him towards the museum. She uses one of her claws to cut a hole in a window...

...and she and Harry enter. Harry finally manages to stop flying, and the two head towards the ring. Felicia smells something, and says this could be dangerous. She tells Harry to promise that if anything goes wrong, he's to forget about her and run. Harry refuses, but they then hear the sound of some glass shattering.

They see that Morrigan has smashed open a case, and goes to take a ring. But Felicia jump kicks her, and tells Harry to get the ring, whilst she holds Morrigan off.

Morrigan gets up and fires out an energy blast, which Felicia jumps over. The blast hits the case, destroying it and sending the rings everywhere. Felicia continues to fight Morrigan, but gets kicked down.

Harry starts looking at the different rings, but can't find the one he wants. Morrigan yells at him to give her that ring, and throws out another projectile at him. Felicia jumps in the way of it, and gets hit.

She hits a wall, and then transforms to her smaller cat form. As Harry checks on her, Morrigan again demands he give her the ring. Harry tells her to go get it, and tries to throw it out of a window. But Morrigan flies over and grabs it in the air.

She says the ring of blood belong to Morgan le Fay, the greatest sorceress of all time, from whom she is descended. But it needs the blood of a Darkstalker to awaken its powers, so how convenient for him to bring one. She traps Felicia in an energy net. Harry tries to use his powers, but he just starts floating uselessly in the air. Morrigan laughs and calls him an inept little boy wizard. She hopes he wasn't planning on growing up!

She fires another energy beam, which is about to hit Harry, but Donovan then appears and blocks it. He says he's the dark hunter, and tells Morrigan she can't escape him -he can track her to the ends of the Earth!

Morrigan says she won't make him go that far, and warns him that the next time they meet, she'll be the hunter. She starts spinning around and disappears, but creates a vortex which starts to suck Harry in. Donovan uses a technique to save him.

Donovan says that was a short-range displacement spell. He asks Harry if he's alright, as Morrigan is far too dangerous for someone of his age to face alone. He asks who he is, and who his mentor is. Harry introduces himself, but says he doesn't have a teacher, he just has Felicia. Felicia has been taken by Morrigan, and Donovan explains that Morrigan is a succubus -she drains the life energy of others to increase her own life force. Harry says Morrigan needed Felicia's blood, so they've got to find her and stop her. Donovan tells him he has nothing to fear, as he'll track them down and destroy them. The Darkstalkers will fall before him! Harry says he doesn't want Felicia harmed.

Donovan says Felicia is one of them, an enemy of human kind -they must all be destroyed! Harry says Felicia is his friend, who saved his life, and he wants Donovan to take him to her. Donovan says no, as he can't endanger him. As for where they've gone, his spell sword will find the trail of Morrigan's aura. As Harry moves back, he hits the ring he was after.

He picks it up, and then watches as Donovan creates a portal. He puts the ring on and says he has the power... but it does nothing. He wonders what the point of a magic ring is if it doesn't do anything.

He then sees that Donovan has gone through the portal, so he quickly jumps through it as well. Meanwhile, Morrigan has taken Felicia to Glastonbury Tor, and tells her this will do. They claim King Arthur was buried near this hill, and this is a most ancient site of mystical power, making it the perfect place for the ritual. She doesn't like the tower though, and it offends her. She decides to temporarily rearrange things.

She throws out a projectile, which causes the tower to collapse.

Morrigan says that Pyron has ordered her to bring him all the other Darkstalkers alive, but she needs his blood to awaken the ring, which will make her invincible. She thinks this is a no contest -she needs to keep her priorities straight. Before she can stab Felicia, Donovan and Harry appear. Donovan tells Harry he shouldn't have come, and orders him to stay out of sight. He runs towards Morrigan, so she unleashes a projectile.

Donovan blocks it, and then counters with a massive energy wave. Morrigan gets knocked back, and this causes Felicia to be released. She reverts to her usual form, and finds Harry. She sees he has the ring, but asks who the hunk fighting Morrigan is.

As they watch Donovan blast Morrigan, Harry tells Felicia who he is. Felicia tells Harry to stay here whilst she gives Donovan a hand. Harry tries to warn her, but is too late. Donovan blasts Felicia as she runs towards him. Harry tells Donovan to leave Felicia alone. Donovan says he told him to stay hidden, as he can't let him come to harm. Harry tells him he hurt Felicia, but she wasn't after him. Donovan tells him he can't trust these creatures -the catwoman is his enemy, the same as Morrigan!

He says he has a sacred vow to fulfill, and goes to strike Felicia. Morrigan gets up, and notices a cut on her finger. She decides to use her own blood, and places the ring on the wound.

The ring shines brightly, and the spirit of Morgan le Fay appears. Morgan asks who called her, and Morrigan introduces herself. She says she's called upon her to help her destroy her enemies. Morgan asks where her greatest foe is -where is Merlin? Morrigan laughs, and reveals that Merlin has been dead for centuries. Only the three behind her stand against them. Morgan calls them worms, and tells Morrigan that her power is hers. Donovan tells Felicia to get Harry to safety.

Felicia and Harry move back, but Felicia tells Harry to activate his ring. Harry says he doesn't know how, as Elijah didn't write that part down! Donovan attempts to fight Morrigan, but is easily blasted back. Felicia tries to attack, but Morrigan enlarges one of her hands, and swats Felicia aside.

Morrigan tells Harry he's next. Harry says he won't let her hurt them. Morrigan asks him what he can do, and Harry says whatever he has to do -she won't get past him! As Harry says this, the spirit of someone appears above them. The spirit is of Merlin, who says he is the enemy of all that is evil in this world and beyond.

He tells Harry that his courage has awoken him, and the fires of his will have been lit. He tells him to learn now that the ring has no power, the power is within himself. He then tells them to behold, and shoots an energy blast at Morgan, destroying her.

Morrigan collapses, and as she does, the ring of blood vanishes from her finger. Merlin tells Harry to never stray from the path of truth, and his power will never fail him. He tells him farewell, and vanishes.

Morrigan gets up and asks for forgiveness, as she had no idea he was a descendant of Merlin. She asks him to join her, as there is much she can teach him, and much mystic knowledge they can share. Harry tells her to share this, and uses a magical stink bomb on her.

Morrigan calls him a miserable brat, but before she can do anything, Donovan and Felicia confront her. Morrigan realizes she's in trouble, and begs Demitri for help. He appears and asks if she's begging for help, as it's unlike her. Morrigan wants him to get her out of here now, so he has her beamed back up to the ship.

The entire area starts to shake, and the tower magically puts itself back together. Donovan says his spell sword can no longer sense the trail of Morrigan's aura, and whilst she's escaped him, he vows to find her again. Felicia says that's fine by her, but this was a serious night's work.

Donovan says this night isn't over, and goes to attack Felicia. Harry says he's telling him this for the last time: Felicia is his friend. Donovan tells him that he'll respect his wishes, but says he can't promise it'll be the same when they meet again. He then creates a portal beneath himself, and sinks through it.

Felicia thinks Donovan is a jerk, as he could have at least let them hitch a ride back to London. She asks Harry if he knows any handy teleportation spells in his pocket, but Harry says he has the next best thing: his dad's credit card. Felicia wonders if Harry should have gone with Donovan, as a sorcerer like that could teach him everything he needs to know. Harry doesn't think he and Mr. humor-impaired would get along so great. And besides, Merlin had said the power was within him, so he'll figure it out by himself.

On Pyron's ship, Demitri asks Morrigan what danger was so terrible that she was forced to ask help from him. Morrigan says that boy the catwoman is dragging around is a descendant of Merlin. Demitri scoffs at this, and asks if she's afraid of a mere human boy. Morrigan says Merlin was there, and not just him, but another human who's big trouble: the dark hunter, Donovan Baine. Demitri asks if she's sure, so she asks him if he's afraid of a mere human wizard. Demitri turns around and sheepishly says he fears no one.
