He is stooped with a grey beard.
Ulmer was once an outlaw and member of the Kingswood Brotherhood. Ulmer claims he once put an arrow through the hand of Lord Commander Gerold Hightower, the White Bull, in order to steal a kiss from a Dornish princess - most likely Elia Martell. He also stole her jewels and a chest of coins. Ulmer helped Wenda the White Fawn burn her mark in the buttocks of her highborn captives, such as Merrett Frey. After the destruction of the Brotherhood, he was sent to the Wall, and is presumably the last survivor of the disbanded organization.
A Storm of Swords
Ulmer is part of the Great Ranging, the force that leaves Castle Black and the Shadow Tower in search of Benjen Stark and Mance Rayder. He survives the Battle of the Fist of the First Men. Ulmer stays loyal to the Watch during the mutiny at Craster's Keep and was one of the few survivors of the ranging to make it all the way back to Castle Black.
A Feast for Crows
Jon orders that the garrison of Castle Black practice the bow under the guidance of Ulmer.
A Dance with Dragons
While discussing his archery practice under Ulmer's guidance, Samwell Tarly mentions to Jon that he likes Ulmer's stories and that someone should put them in a book. Jon says that Sam should do it, as there is parchment and ink at the Citadel, where Jon is sending Sam. Jon also expects Sam to continue practicing the longbow at Oldtown with Ulmer's instruction in mind.
The roguish Ulmer gracefully dances with serving girls at the wedding feast of Alys Karstark and Sigorn of Thenn. He commands from atop the Wall when Tormund leads his wildlings through to safety.
