His name was Aldrex'ile'nuruodo, better known as Xilen. He was banished from House Nuruodo and, after IRL years of plotting, he managed to assassinate the head of each Chiss House; Nuruodo, Cspala, Sabosen and Inrokini were the primaries but there were also 3-4 player created houses that he also took down (with their permission). After that, he single-handedly dissolved the Chiss Ascendency, blaming the galaxy at large for the assassinations and launched the first Sovereign Chiss Empire (SCE). It literally held half of the galaxy before The New Order, The Republic, and several other factions spear-headed it all at the same time to stop it.
One of the most fun role plays I've ever done, aside from my Hapan Civil War roleplays.
