Davlin was a big, hefty male black rat, and a captain in the Anaki Ratguard. He was fond of Merrywine, which he drank with fellow officers Yulin, Nevka, and Gerrad whilst celebrating the capture of the noblerat-murderer Rorna.

He was not overly fond of fellow captain Ayid, whom he saw as too soft on the non-rat citizens of Anak and too hard on rats. He supported Yulin as a replacement of Ayid, knowing Yulin was much less devoted to real, fair, blind justice.
