Gah. As I have
NO idea who this Walker Grey guy is this is a terrible terrible tease Henry. Or a terrible terrible cocktail made from Johnny Walker and Grey Goose. Yeah, yeah, I know: you don't drink.
Blah! Anyone out there who this guy is?

As for Aeorin...
I believe the Theocracy of Canceri Book says it was the Sarishian Knives that got Aeorin in its section on "Unholy Champions" (in the section that has the Sarishian Knives write up). If I recall correctly they hid in plain sight to bypass his sentries and abduct him from his tent. But now you have me scurrying back to the stacks to see if I have just made an assumption on reading it, or am otherwise misremembered something.
