The story thus far: Shauna Miller, owner of the Doom Sword, alias the nightly heroine Lady Doom, has been the target of Rageblade and the Night Clan, villains bent on stealing her alien weapon. They succeeded, leaving Shauna weakened.
Now, she has the Sword and her full powers back, and what's more--she's gone totally berserk. Claiming to be the embodiment of the Doom Sword itself, Lady Doom is on the rampage, and only Hal and the Night Clan's Wyvern can stop her. Or can they?
