From Tar Valon Library
A similar entry appears in the Wheel of Time Companion confirming the information available in the main story arc.
Adsalan is a Warder serving the Black Ajah hunters Egwene encounters in the Tower. His Aes Sedai is unknown, but Egwene believes none of the Sitters she meets with has a Warder, so he is likely to be bonded to one of the spies sent in by the Salidar Aes Sedai. He is described as having keen eyes, ruddy hair and a square jaw. TGS, Ch. 12
