Urwyn Mahndrayn was a Charisian citizen and an officer of the Imperial Charisian Navy.

Holding the rank of Commander, he served in the Experimental Division, working on explosives and new rifle designs. However, before he could see their mass production, he was murdered by his cousin, Trai Sahlavahn, a Temple Loyalist bent on sabotaging the Hairatha Mill. (HFAF)

The new breech-loading rifles he designed were named Mahndrayns in his honor. (MTAT)
