Once upon a time, when Wizards of the Coast was publishing L5R, Shokansuru (not Daigotsu) was going to be the main bad in the original plotline for Gold Edition/The Four Winds Era. Howevever WotC dropped the game, plans changed and this storyline was dropped. Who was Shokansuru in this version of the story?
Probably we won’t ever know…
We had first meet this Shokasuru character sometime before, during the Fire and Shadow (in Hidden Emperor era). It seems like Feydn Rafiq (an assassin from the Ivory Kingdoms, in the Honor Bound set). The Rafiq were a corrupt House of kshatriya caste (the IK equivalent to samurai), devoted Ruhmal cultist. Feydn travelled to Rokugan in a failed attempt to propiciate a coup within his House, by sabotaging a major plot in Rokugan. At some point in this operation, he allied himself with Shokansuru. Let’s say this ended badly, both for Feydn and for Balyezn, another member of his house.
In any case, this Shokansuru/Onisu direction initiated at WotC was scrapped by the new Story Team lead by Rich Wulf and Shawn Carman: Daigotsu became the main antagonist starting with the Four Winds era. Shokansuru eventually got his own story, and the Rumahl plotS would eventually develop in world changing events that would affect Rokugan for years to come!
