Is he still lurking around? He kind of seems like the ideal candidate for this...
Who? Onamont or Cyrilos?
Cyrilos is co-leader of the Way of the Warrior Saints in Eston, and the recently-appointed Duke of Belegrond.
Cyrilos would be PERFECT for some kind of sorcerer's secret society. But he's got a pretty solid story rolling on Atamara right now. Maybe at some point in the future he'll be ruined there and find himself needing a refuge.
