Raest was a Jaghut tyrant who was imprisoned with his finnest in a barrow in the Gadrobi Hills when his own people formed a truce with the T'lan Imass.

In Gardens of the MoonEdit

He was released by Adjunct Lorn and the Imass Onos T'oolan so that he would attack and weaken the defenders of Darujhistan, allowing the Malazan Empire to conquer the city quickly and efficiently. After a battle with Silanah and Anomander Rake's Tiste Andii sorcerers he possessed the body of Mammot, but was subsequently imprisoned in a new Azath house, the Finnest House, in the city.

In Toll the HoundsEdit

He became the keeper of the Finnest House and was given an undead white cat, Tufty, as a gift.
