The Shadow Assassins have never been in a hidden magical realm called the Second Realm, until they were called in by a teacher from the Moonriver Academy for the Supernaturally Gifted. Following the destruction of the school, three united armies stand against the mad King Emeralde's soldiers - the remains of the Moonriver Academy, the werecat tribe Kkyathi and the elf colony of Oraldine. King Emeralde's army runs rampant, no longer controlled by a man losing his mind. In the midst of the chaos, the Shadow Assassins and their two guides separate from Prince Erik to make their own journey across the sea to the Isle Dark, following ancient lore about the Dark Witch Liliana, to see if she is the mysterious being who attacked them as they landed in the Second Realm - and to see if she is the dark force behind King Emeralde's madness. As strong as the bonds are between the Shadow Assassins, even they feel the strain of their travel upon them. Crossing into the Isle Dark is not an easy journey, with the opponents in their path. Loyalties are questioned and declared. The Shadow Assassins must stand tall, even as the Dark Witch Liliana's influence spreads further and threatens to undo the very bonds that their friendship holds dear.
