I say if WOTC wants to license Wilderlands from Bob Bledsoe by all means do so.
I'll most likely stick with what James Mishler is going to do for the Wilderlands (under the C&C license), but it won't hurt to see what spin WOTC puts on the WL.
Oh, *from* points of light. Heh. I thought it was more like "the characters are points of light (. . .)". Well then. I might have got part of it right, and the other bit (heroes being rare or such). . . just ignore that.
