Chuul Chitinous Servant of Primeval Powers Habitat: Coastal, Swamp, Underdark Treasure: Random Magic Items - Relics Chuuls originated in forgotten ages when aboleths and stranger beings ruled alien empires beneath the waves. The aboleths transformed numerous deep-sea predators into servants that could venture beyond the seas to claim more magic and creatures to exploit. Chuuls are the most enduring of these bizarre servants. Many chuuls serve aboleth overlords, carrying out their whims amid lightless seas and primeval swamps. Other chuuls obey new aberrant masters, such as beholders, grells, or mind flayers. Some chuuls follow their own drives, endlessly collecting ancient magic treasures or interpreting age-old orders to bizarre ends. Regardless of their agendas, chuuls snare creatures in their massive pincers before rendering foes helpless with their paralytic tentacles. Chuuls don't age and can lie dormant in hidden places for millennia before threats, ancient orders, or strange compulsions awaken them. Aberration Large 30 ft., swim 30 ft.
