Arbrin was one of the village elders of the Mud People.
Arbrin was amongst the village elders who refused to grant a Gathering for Richard Rahl. Richard returned the lives and honor to the elders after Siddin was almost killed by spirits summoned by the Night Stone. Arbrin then confirmed Richard and Kahlan as Mud People and took part in the gathering that Richard requested.
Arbrin later took part in another gathering requested by Richard.
