From Lost Fables Wiki
None who have faced a Charybdis beast close enough to gaze upon its form have survived to tell of the experience, their lives and their stories swallowed by the briny depths. Charybdis beasts are (probably) huge monsters that (definitely) create massive, destructive whirlpools during rough lightning storms at sea. It’s said that they attract lightning, so if you see lightning at sea begin to rapidly and repeatedly strike in the same area, avoid that place at all costs, for if the Charibdys Beast senses something of suitable size above it, it somehow generates a massive whirlpool to suck its intended prey down. If you see these lightning strikes walking towards you on a stormy night, frequently the only thing to do is pray.
Can create massive whirlpools.
