Deadly Beasts. Brutal combat. Welcome to Avantia.

At the age of seven, Tanner's father was killed in front of him by the evil warlord Derthsin. But his father's death was not in vain and Derthsin was carried away to his doom by a good Beast, Firepos the Flame Bird. Now, eight years later, another evil army is wreaking havoc across Avantia. But Tanner has been training with Firepos, waiting to avenge his father's death. There is something familiar about this new menace, who rides with a Beast of his own. The evil army is after the pieces of the Mask of Death--which allows whoever wears it to control all Beasts. Tanner sets off on a journey to stop them. Along the way, he encouters twins Gwen and Geffen, who hold the map to finding the remaining pieces.
