Although Oliverius is still building up his Arts to get to a better level, this is the next project he'll be working on, because I'm crazy. He wants to start experimenting to see what the effects of this obscure concept are; what a sword made of the mind can actually do, the effects of having your anger forged into a blade. There are deeper concerns, like what happens if the blade is sharpened or tempered, or even broken, but that is for the future. He wants to explore these possibilities. Oliverius isn't sharing the full plans with his covenant yet, of course, Verditius are secretive.
He would also like to see if the Redcaps could get him a lab text for Inmost Companion.
silveroak, is this a project that may be well-pursued by the game, or is it a bit too weird for your plans?
