Gug are twisted giants that roam the Underdark and sometimes above the lands in dark caves. The gug came from the plane of freaks known as the Far Plane but they worked their way upon Esperia in the deep realms. The gug is a nomad like creature but some races of the dark have used them as guardians and slaves such as the drow, duergar, mind flayers and the derro. The towering gug is large in size and has four sets of arms and a vertical fanged mouth that splits its head into half. The gug speaks its own language but they can speak and understand undercommon also.
Some gugs have gained enough power through time that they become priests to the twisted demi god known as Tharizdun.
