About
Anyone who's invested time and effort into getting to know Arlin Fiddlehead would learn not a lot more than he's a PITA that doesn't like thinking about his past. What one may find out about him are the following.
He wears robes over a full suit of chain, a long sword on one hip and the Book of Bahamut on the other. He's always seen carrying his holy symbol, a shield with Bahamut's head as the charge.
Arlin is 7 foot tall, 3.5 foot wide and 300lbs. He has blue skin and eyes, shorter than shoulder length white hair, 2" long full beard and a resting grumpy face.
Arlin does not evangelize. If he's doing the talking, negotiations have fail or something has gone terribly wrong.
Arlin is not on the right path. He believes that he's only redemption is by proving himself worthy of the Rite of Rebirth and he's on a mission from the Temple to do. He's wrong.
Arlin should not drink. He won't stop. It'll be extremely bad. People and things will get broken and he'll probably have, what looks like a mental breakdown. It's not pretty.
If Arlin doesn't do his kata meditation and completely dead exhausted, he won't sleep well. Not sleeping will make him grumpy...er.
Arlin seems to have a bad reputation, especially where alcohol is served. He likes getting into fights, there's something his previous life and he should NOT DRINK!
History
Arlin is particularly closed-mouthed about his childhood. On the other hand, he loves sailing and the last captain he served under and talk about either for hours.
