Cohlien Frostweaver is a male gnome mage who can be found in Netherstorm [[:File:|[, ]]] who belonged to the Kirin Tor while still alive. He died when Kael'thas' forces attacked the village. Frostweaver is one of the four spirits that can be put to rest in Kirin'Var Village. When his spirit is killed he drops [Cohlien's Cap], which starts a quest.
