The Rehda tribe is a tribe that worships Alma whom they believe they were descended from. The people and culture of Rehda are referred to as Rehdan. All of the Rehdans encountered by Adol live on the Canaan Islands but it is not known if more live on the unexplored regions west of The Great Vortex. Most of the Rehdans are living secluded to the Rehdan Village on Quatera Island after the increase in the Eresians population on the Canaan Islands.
The Rehdans' most distinct features are their pointed ears and tail which greatly contrasts with all other races introduced so far.
