My players came across Bokken's hut recently. On a whim, I changed him into a dwarf. A drunk, crazy dwarf. I've been playing him as constantly alluding to various exploits and adventures, much like the Most Interesting Man in the World from the Dos Equis commercials. He also believes that one character is royalty, and another is a former lover.
It's been a lot of fun so far. He's showing up for (and now helping plan, it seems) their Taxfest game-time a week game-time. I can't wait for him to interact with Kesten. Svetlana is quite fond of him, but Oleg doesn't have any patience for him whatsoever.
