Morning Mist is a female wolf. Her true wolf name is something along the lines of an image conveying "a frosty morning with the bite of snows yet to come already in the air, and the mist curling thick across the valley, swirling with the sharp breeze that carried the promise of good hunting".
When the camp of the Dragon Reborn is attacked by Trollocs, nearby wolves help in the defense of the camp, Morning Mist among them. Afterwards, a group of seven wolves track down a Myrddraal and kill it, but Morning Mist is the only wolf to survive the Myrddraal.
