Nearly insane, Blibdoolpoolp the Sea Mother is patron of the declining subterranean race of kuo-toa. She hates humanity for the ancient wars that drove her race underground, and is well pleased when her followers sacrifice them to her. She is rumored to know great secrets of ancient magics, but in her insanity, she shares them with no one.

This month features the second of the four centaur deities that were listed but not detailed in an old Dragon Magazine articles on centaurs. Fanthros Storm-Hooves is the patriarch of the small clan of four deities, who all serve under Skerrit the Forrester. Among the small centaur pantheon, Fanthros is the deity of weather, the sky, and agriculture.

Another great entry and keep up the good work. Your work is an inspiration for my own 5e updates to demigod, deities and epic monsters in general. But I have a long way to go to match the breadth and depth of your work. Thank you for sharing!
