Greid was the third son of a wealthy farmer. He didn't enjoy the prospect of sharing his father's lands with his two surviving brothers so he went off to find a better way of life.
Though only newly attached to Arthur's teulu, he has already shown that by personality and size he is a fit companion for Rhun in his capacity as protector in battle. He was easily dispatched in the mock battle against the seasoned warriors, but fought bravely in his first battle and was protecting Arthur in the battle against Ceredig in front of Luguvalium.
Quiet, sturdy, and readily accepting of his self-designated teacher, Rhun.
