Ori

From the Lyorn Records of the Dragaeran Empire

A sorceror in the employ of Fornia. A nasty piece of work who attacked Vlad Taltos in his home. Ori's attack was intended to intimidate Vlad into staying out of the upcoming war between Fornia and Morrolan; this backfired seriously.

Vlad later stuck a knife in Ori's back, seriously cramping his style.

(Also, see instead Ori of Smallcliff.)
