Night of Shadows

Ninja are hired to depose tyrants and protect kings, but they arent just assassins. The ninja have a sacred covenant, by which they guard the world from shadows.

Isamu Raidens family have been the keepers of this Covenant for thousands of years and the time approaches where this task will fall to him. He has one last mission as an apprentice. He sets out, with his partner Amaya, but when he returns home, things have gone terribly wrong. His clan and family are dead. The ninja responsible plans to break the Covenant and free the Shadow Warrior, plunging the world into darkness.

With Amaya at his side, Isamu pursues the ninja in hopes of catching him before he can reach the Shadow Warriors prison. All the while knowing, if he fails, there is no hope for the world.
