Grimslaak was an ultroloth agent of Yrkhetep in Chondath in 1358 DR.


In 1358 DR, Grimslaak killed and replaced the innkeeper of the Inn of the Five Crown in Arrabar in order to spy on the meeting of the Sisterhood of the Oaks, the Lightblades, the Sunshafts, and the Windriders, where they organized their battle plans against the troops of one of the Yrkhetep's minions. Eventually he sent three yagnoloths to kill possible disturbers.[1]
