Gong is an unusually smart and eloquent pusk, a sloth demon. He is unequivocably evil, but he's also a sleepy little guy. Bad to the bone, but lacking the capabilities to back up his maliciousness, he sleeps for 20 hours a day and grumbles about his existence.
Gong encountered a Ghaash'kala patrol in 999 YK that destroyed him. He remembers the face of the shifter who killed him.
He later encountered the same patrol in Eyre of 999 YK, and avoided another fight with them.
