Changes from L5R canon

Shiro Heichi has a number of changes from official L5R canon.

Minor Clans.

The Bat, Monkey, Ox and Oriole do not exist. The situations that resulted in them in L5R canon happened, but no clans were granted. Toku was still a much respected warrior, but was adopted by the Seppun. His line is still respected and admired.

Enlightenment

The Enlightenment era of the CCG never happened. Enlightenment was not handed out to dozens of people, and the Crane as a whole were never enlightened. The Keepers of the Elements and their books never existed. The Badger were still aided in recovering by several non-Badger.

Togashi and tamashii

Togashi was a damn dragon and a god. He didn't need to steal bodies like Yajinden and Iuchiban.

Yotsu

Yotsu was rewarded with his own Seppun vassal family. To prevent a similar situation from ever occurring again, his family is tasked with keeping tabs on travel routes within the empire, advanced scouting and trailblazing to make sure the Emperor and his family are never ambushed again. If the Yotsu daimyo ever makes a suggestion or argues against a propsed travel route, the rest of the Seppun and the Emperor heed him, except in the most dire of circumstances.

Spider

Daigotsu's Spider 'clan' attempt was exposed by Kitsuki Iweko, thus proving her worthy of becoming the new Emperor of Rokugan. After the failed attempt at infiltrating Rokugan, which led to the destruction of much of Daigotsu's Lost and nearly all of his unTainted followers, Daigotsu has kept to the Shadowlands, and has not been heard from for a long time, something that worries the Crab.

Iweko's ascencion

Kitsuki Iweko was proclaimed Emperor and founder of the new imperial dynasty of Rokugan by heavenly proclamation. She was not given a zap of omniscience, speaks like normal people, without telepathy, and without making sock puppets of anyone, let alone Togashi reborn (Satsu).

The War of Dark Fire, the Destroyer War/Kali-ma, Second City

This does not happen. The War of Dark Fire might possibly occur in some fashion in the future, but the rest of this does not.
