Trying to do a lot with a lot on my plate but... slowly but surely.... will make it through these mermay prompts.... *strength pose*

Anyways, for this prompt, I wanted to do like... a sea medusa... but then I was like... no head only snakes that are part of a whole being and when that being speaks, it sounds like multiple people are talking. The weapon this being has is an old and important one that it will only give to an honest soul. You'd think you'd be able to tell the truth in front of this thing, but the first rule of the Sea is that you shouldn't blindly trust whomever you meet...
