Corlan Dashiva
From A Wheel of Time Wiki
Corlan Dashiva is an Asha'man, chosen by Rand Al'Thor to be one of his bodyguards after being kidnapped by the White Tower Aes Sedai under Elaida. Unknown to Rand, this man is actually Osan'gar in disguise.
Dashiva and several other rogue Asha'man, who turn out to be darkfriends, attempt to kill Al'Thor and flee, while Al'Thor then follows to try and kill the would-be assassins.
A farmer, Dashiva appears to be going insane due to the taint on saidin.
