Zeeny-Deedle is actually a nice guy if you get to know him and haven't given him a reason to think you need to serve some penance.  The scars, mottled skin, tattooes that are cut in half and married up to other tattooes can be a little off-putting on first impression though.  Once you get to know him though, the thing you remember is the strange eyes that seem hollow.

If you manage to become a friend to Zeeny-Deedle, maybe he will tell you about when he lived in a bottle on the desk of a famous alchemist but don't get your hopes up.  Zeeny isn't a drinker and that story needs a pitcher or maybe even the whole barrel of ale.
