He was very young, stocky with only a few blotches.
The Black Tower Edit
When Rand al'Thor and Mazrim Taim begin testing the men to see if they could channel, he was keen to find out. He had reached the rank of Dedicated. He had placed a bar on himself and believed he couldn't affect anything at a distance with saidin, so his strength decreased the further away he Channeled.
He fought in the Battle of Dumai's Wells and accompanied Rand after the battle back to Cairhien. He was brought to Caemlyn to act as a Traveling messenger between there and Cairhien. Along with the other Asha'man in Rand's entourage he helped him in the conquest of Illian.
The Seanchan and madness Edit
Later he was sent to Altara by Rand to spy the Seanchan. He felt the strangeness of the One Power near the destroyed farm of the Kin. He was very discreet but was discovered one time, fortunately he was able to destroy all the proofs of his doing.
He reported to Rand with extreme accurancy that the Seanchan were planning to invade Illian. He returned to Rand with word of the Seanchan preparing to move from Ebou Dar soon they put soldiers along the Venir Mountains all the way to Arran Head. When Rand praised him, Morr mentioned there had been some talk about an "Aes Sedai weapon" (the Bowl of the Winds and following unweaving explosion of a gateway). He investigated the ground where it was used and felt saidin being worst there; he said he could feel it in the air as if it were alive. Morr insists upon not being mad, and Rand assures him he will live until the Last Battle
He had just been promoted to the rank of Asha'man by Rand. He rode with Rand when Rand's forces attacked the invading Seanchan just outside Illian. He Healed Rand when Rand was struck by a crossbow bolt. On arrival back to Cairhien he accompanied Rand to his meeting with Cadsuane Melaidhrin.
When the rogue Asha'man blew up Rand's quarters he got Morr to guard Min Farshaw with his life. When Rand arrived back, Morr had finally succumbed to the madness of saidin and had the mind of a child. Rand slipped some poison into Morr's cup, putting Morr to sleep forever.
