The Grimscale tribe is a tribe of murlocs found on both the Golden Strand and Tranquil Shore in the Eversong Woods. They are led by Mmmrrrggglll. They are involved in a few quests. Interestingly, there are some undead former Grimscales in the Ghostlands. They are involved in the quest The Plagued Coast in which it is said that, like the Forsaken, "they've retained free will in undeath" also.
