Wilson was actively spying on and sabotaging Arcachon for, if I recall correctly, three real life years, from the fall of the first Sartania.  He was the one who made sure that Tuhpos and other regions kept revolting so Arcachon couldn't hold Niel, which made Jenred invoke the treaty clause where Arcaea got Niel if Arcachon couldn't hold it, leading to the first (under Jenred) Arcaean/Arcachonian war.  He passed crucial information throughout every war since the fall of Sartania to any opponent of Arcachon's he could find via various Sartanian contacts, egged on the last Arcaen/Arcachonian war from Arcachon's side, and kept the rebellions in Arcachon going for at least twice as long as they would have otherwise, which is what finally crippled Arcachon enough that they could no longer effectively fight.

Absolutely brilliant.

Aww Bedwyr, you know how to make a guy blush.
