Throne of Darkness is a Japanese-themed action role-playing game released in 2001 by Sierra On-Line, a subsidiary of Vivendi Universal Interactive Publishing.
The game is set in Yamato, a medieval version of Japan ruled by the shogun Tsunayoshi and the daimyō of the four clans.
Zanshin's forces sweep across Yamato one night, catching the clans by surprise and annihilating them.
As dawn breaks, the daimyō decides to counterattack, ordering his seven surviving samurai to destroy Zanshin and his minions.
The four clans and daimyō are named after historical Japanese clans and persons: Gameplay resembles Diablo II, as many of the game's developers worked on Diablo.
