The conflcit ended when Jac Cotelin slew the clone and restored order to the shattered clans.
History
In the middle of 25 ABY internal relations within the brotherhood broke down entirely. Many of the clans accused others of sabotage and unsanctioned infiltration. Within weeks the situation escalated with several openly declaring war on others. Into the chaos stepped Jaac Cotelin, a clone of the Grand Master, declaring himself to be the rightful Dark Lord of the Sith. Having been on the brink of conflict for several months the brotherhood descended into civil war. Unable to distinguish one from the other many clans ended up taking sides, others simply watched from a distance in the hopes the two Grand Masters would destroy each other.
Jac Cotelin gathered forces from the clans still loyal to him to Antei while the clone assembled an army and prepared to launch an all out assault. After several months of preparation Jaac Cotelin launched his assault on Antei, his fleet descending on the ships amassed to defend the brotherhood's homeworld. After breaking through to the surface the imposter's army descended on the Dark Hall, taking the battle right to the steps of the Star Chamber itself.
In a final test of lightsaber against lightsaber, Jac Cotelin slew the clone restoring order to the brotherhood. However, the damage was done regardless, trust between the clans remained unstable and much of the Dark Hall stood in ruins.
