Mathlann

As the lord of the sea and God of Storms, Mathlann is patron to sailors and explorers, and is prayed to by Elves about to embark on a voyage or seeking new lands. He is also prayed to by the loved ones of those Elves who are abroad so he will bring them home safe and sound. Mathlann is one of the main Gods worshipped by the Elves in Marienburg.
