Isn't he the guy who played half a realm...?
More like half of two realms.
He was half of Irombrozia (the half that favored rejecting peace with Riombara back when Irombrozia appeared to be winning and maybe could have had peace) and about 2/3 of Aquilegia.
He doomed Irombrozia before he even closed his accounts; but he killed Aquilegia when he left.
