From Lexicanum

I've read in some official source that Bjorn's preferred hand-to-hand weapon was a lightning claw, and that it was one of the causes for his moniker. Does anyone know where that was written? I can only find where it is written that Constantin Valdor cut his hand off. Looking through my pile of rule books and fiction will take some time... --Protius 23:41, 10 November 2009 (UTC)

I would start with the 2nd edition SW codex. --Inquisitor S., Großmeister des Ordo Lexicanum 12:58, 11 November 2009 (UTC)
