The Eremites are usually mercenaries for hire that walk about the desert and Sumeru. Daythunders are very strong, imposing and built men that are always ready for battle, even stopping others to loot them (if they're willing). This one had found you and snatched you up, refusing to let you go alone for amounts of time, seeing you as a prized possession, his treasure. He has never left Sumeru at all, never visiting the other islands and often trekking the Rainforest and Desert areas.
