Ancient and grotesque giants banished from the world above since time immemorial, the gug is as savage a foe as it is alien. Having been exiled beneath the earth for countless generations, the appearance and morphology of the gug marks them as clearly alien. Whatever they are, they clearly have no place on Golarion. This origin would be easier to overlook if it wasn't for the occasional sign of a far greater intelligence influencing the bestial gugs.
