Talthressar was one of the elven lieutenants serving under Alleria Windrunner during the Alliance Expedition's invasion of Draenor. With Verana's return to Quel'Thalas, Talthressar presumably took up the mantle of Alleria's right hand. When Alleria followed Khadgar to the Blade's Edge Mountains, Talthressar was left in charge of her high elves. Alongside Danath, Herrick and Rellian, Talthressar hunted Ner'zhul through Terokkar Forest. In all likelihood, Talthressar is dead, or he is now in the company of Alleria and Turalyon, having vanished along with them to wherever it is they now tread.
