Yaevinn is an elf and a member of Toruviel's Scoia'tael commando. He also has his own commando in the vicinity of Vizima. He has a greater penchant for flowery words and metaphors than most elves, perhaps rivaling Dandelion alone in his prose. Yeavinn participated in the second war with Nilfgaard. During the Battle of Brenna, he was Lieutenant Colonel of the Deithwen division. He was seriously injured in that battle.
