Many men can pull off the traditional garb of Boccob's field researchers(wide brimmed hat, long coat, and the armaments necessary to survive the risks inherent in the work), but Quinn is not one of them. He looks more like a child wearing his father's clothes than the skilled hunter of knowledge that he is.
Background:
Quinn always wanted to be a field researcher for the Church. Even if it wasn't a family tradition, the tales of their adventures would have set him down that path. Exploring long-forgotten temples, bringing back artifacts thought lost to time, studying the places to dangerous for anyone else to venture in. Who wouldn't want to join their ranks?
So, Quinn became a field researcher. He explored dank tombs and he liberated tomes from liches and he fought off more than a few attacks by those twice-damned Vecnites. Eventually, he was called on to investigate an abandoned temple that villagers have reported odd lights coming from. What he found within was astounding. It appeared to be a planar rift. The Empire forbid all knowledge of such things, and only the Church of Boccob was brave enough to even secretly speak of them! This was a chance to investigate something truly unknown to all. Then the rift surged forward, and everything went black.
Now, he is stuck in a city called "Sigil". He has no way of returning yet, but he doesn't mind. It just gives him more time to collect information on the lesser-known planes.
