Sundrabad Kumar was a member of the Allhammers who occasionally assisted the party in their endeavors and (more commonly) misdemeanors. He never mentioned his homeland, but from his accent it was plainly somewhere unknown to the peoples of Westerland, possibly the Moonless Lands in the Far West.
Sundrabad frequently bobbed his head from side-to-side when speaking. In conversation, he often displayed many different types of head bobble, though it was unclear to the party if they all had the same meaning, or if each conveyed something specific.
It is unknown whether Sundrabad survived the Siege of the Seat, nor if he remained loyal to Rennick after.
