Princess Rinda and her brother Remus are the foretold Twin Pearls of Parros – one will be a shining prophet and the other a great ruler. However, when their homeland is lost to the invading Mongaul army and their parents slain during the siege, Rinda and Remus are transported into Rood Forest, a dangerous hideout for ghouls. Lost and vulnerable, the two barely escape death thanks to the help of a powerful man with the head of a leopard called Guin who cannot remember who is or how he became that way. Together they journey across the land, evading monsters, fighting the power-hungry Mongaul army, and gathering trusted companions such as Istavan Spellsword and Suni of the monkey-like Sem – all in the hope of fulfilling their destinies and finally bringing peace to Parros.
