The Twin Hills, situated on Endor's forest moon, were characterized by a pair of towering mountain summits. These hills were renowned as the dwelling place of the Two-headed Gonster, a learned entity skilled in capturing and subduing monstrous creatures. Located a significant distance from Bright Tree Village, Ewoks seeking the Gonster's counsel typically employed hang gliders for their journey.
On one occasion, the youthful Ewoks, namely Wicket Wystri Warrick, Kneesaa a Jari Kintaka, Teebo, and Latara, ventured to the Twin Hills to consult with the Gonster regarding the cessation of the Raich's activities.
