Arthaeuil Nrensam

High Trident Arthaeuil Nrensam was a priest of Umberlee at the temple of Onthalasp in the Nelanther Isles in the 10 and 11 centuries DR.

In the Year of the Roaring Tempest, 1016 DR, Arthaeuil wrote an autobiography titled Words on a Wave. It detailed his life and the customs of the Umberlant faith, such as The Orglara and the rites of the Green Priests at the Shell House in Ilyaport, Lapaliiya, but it might be considered biased toward his faith.
