An ancient blacksmith, name's Rodin if you're studied up on fallen angels.

[He disappeared from the underworld not long after he fell, but his weapons are legendary...and apparently his alchemy is pretty good too, since the lollipop has effects similar to the larger variety of Vital Stars.]

He's always done a good business supplying witches and warlocks with weapons and alchemical goods, so I decided to buy one on the assumption that you likely can't heal from serious injuries in a matter of seconds.
