Jimar Chubain is the High Captain of the guards in Tar Valon.
He looks youthful for a man in his forties. He has a pretty face and black hair.
He is injured during the Battle of Tar Valon. He reports to Saerin Asnobar how ineffective his men are against the Seanchan channelers and is told to give Aes Sedai support by hanging back and having all his men use bows.
He is present when Gawyn Trakand carries out his investigation on the mysterious death of Kateri Nepvue. He acts very hostile towards Gawyn, until he is taken aside and is told that Gawyn wants to be Egwene's Warder, not take Chubain's job.
He studies the knife thrown at Gawyn during an assassination attempt on Egwene. Neither man recognizes its make. Gawyn asks him to take some of the former Younglings under his command which he agrees to.
