Challer was a male Human who sat on the Imperial Ruling Council until 5 ABY.
Challer was a member of the Cabal during Sate Pestage's brief reign, and later was a member of the Tribunal, along with General Paltr Carvin and Plumba. He was assassinated by his mistress, who tricked him into drinking poisoned Savareen brandy at the Imperial Hotel in 5 ABY as part of Ysanne Isard's campaign to neutralize the Tribunal.
