Kya: Dark Lineage (2003)

Kya: Dark Lineage begins with the protagonist Kya and her half-brother Frank home alone. In her upstairs bedroom, Kya hears a suspicious noise and follows it downstairs to finds Frank in a previously unknown room in the basement. While speaking about Kya's father, Frank unwittingly finishes a mysterious puzzle on a table, opening a portal which sucks in both Kya and Frank. Kya awakens with three Nativs (animal-like creatures) looking down on her. They are then ambushed and chased through a jungle by feral werewolves called the Wolfen/Wolfun. All but one of the Nativs were captured during the chase. Kya and Aton eventually reach a strange village, called Nativ City, and meets the village leader Atea.

Atea explains that the Wolfen/Wolfun are merely Nativs mutated by Brazul, Kya's father. Kya resolves to save Frank and is introduced to Akasa, who teaches her how to fight using mystical bracelets which greatly enhance her strength. Kya is blessed with a power which allows her to exorcize unconscious Wolfen/Wolfun and transform them back into Nativs.

In return for freeing the excorcized Nativs, Atea agrees to help Kya find her half-brother. Kya learns she must find a magical medallion which will allow her to return to her own universe. The medallion was split into seven runes, emblems made of pure energy, which must be housed in a special amulet. During the course of tracking down the runes, Aton leads Kya to an industrialized area dedicated to mining magical amber. Aton betrays Kya, allowing Brazul to ambush her. During the course of the fight Kya collapses part of the mine to escape.

Eventually she discovers that Frank is being held in Brazul's laboratory, and she assaults the complex to rescue him. Upon arriving in the lab proper, she is horrified to learn that Brazul has turned Frank into a Wolfen/Wolfun. Kya defeats the Wolfen/Wolfun Frank and performs the exorcism ritual which returns him to his human form. Kya goes on to gather the last runes required to return home though she is ambushed again by Brazul, who takes the seven runes from her. Kya learns that she is a half alien and she escapes her imprisonment.

Kya journeys to Brazul's fortress,she fights and knocks out Aton who is now a Wolfen/Wolfun but when she gets the chance to exorcise him she doesn't because of falling, heavy crystals.Kya then heads for Brazul and the runes.After a difficult battle, Kya defeats Brazul and returns victorious to a cheering Nativ City, where she activates the portal and finds herself in a desolate place which is not her home. Kya and Frank are in a desert island and are attacked by a creature.

The story ends here, but if all the wolfens are all exorcised it cuts to the credits.
