Temrin plays a critical role in the solving of the teleportation problem and takes part in the ritual to create the anchor. He seems to be interested in gaining knowledge and is the one to tell the player that he or she has to stop the beam from destroying the second tower during the Rune Memories quest.
He is the first character to use the phrase "May knowledge guide you.", whereas the other masters used greetings taken from the God Letters.
He was working on chronicling all of Gielinor's history and reached the dawn of the Second Age before he died.
