Kasuga

Agasha Kasuga was the Dragon Clan shugenja who helped the gaijin survivors of the Battle of White Stag and Battle of Raging Seas escape Rokugan following the battles.

Upon his return to Rokugan, Kasuga requested, and received, a private audience with the emperor. It is not known what Kasuga said, but afterwards, the emperor pardoned him of his crimes and granted him and his followers minor clan status. (3E p.12)
