Lord Kotak seeks to usurp the throne of Arria and destroy King Womba with magic he inherited from the evil Doomba. He’s hired an assassin griffin to attack Lord Fobata, and sowed dissent among the royal guards.

Secluded in the dungeon, the wizard Yaggee aids Kotak and teaches him how to use his powers in secret. Kotak has also hired the bandit Shama and his gang to steal Tau’s Cup, the grail of the gods, from Basha, the lion of light who destroyed Doomba.

Years ago, Basha and his wife Monika survived a dangerous quest along with their allies to recover Tau's Cup. Everyone separated and they’ve settled down since then. After a devastating attack, Basha and Monika must recover what has been lost and seek revenge.

They need help to track it down. They head to the village of Coe Ryn and meet Ringla, finder of lost things. A young man named Eldo, hiding secrets of his own, is forced to join them.

For Basha and Monika can’t continue alone with the challenges that lie ahead. More friends, old and new, come along and they face difficult choices as they approach the capital of Coe Kiki.

They might have to make the ultimate sacrifice as the palace is attacked and barricades rise up on the city streets. The Grail Curse is real, and it will strike them down.
