The Ryric Rebellion took place in 35 ABY when several members of the Sith Council decided to revolt and take power for themselves. Ryric, Rica, and Larsid were the main instigators of this rebellion. They were defeated in a bloody series of battles. Unfortunately, several casualties including Lord Draco were suffered in this short revolt.
Out of Character InfoEdit
Due to several events that led up to Ryric, Larsid, and Rica resigning almost at once and leaving the site, it was determined (much later) that the in character explanation was that they had decided to revolt. Couple that with Draco's no longer coming to the site due to being busy, Kracor and Trivas decided to invent a coup attempt led by the three. To explain his absence and decision to leave the site, Draco's character was killed in this coup with his permission.
