Khastu is an original deity of mine. This is an original piece of art that came to mind as I was worldbuilding, just in time for Mermay was well. Hope you enjoy!

"The oceans of Aivis are both tame and wild, their nature chaotic and free spirited, like its inhabitants. Mortals are able to navigate the oceans as they please, so long as they respect the waters. And there are few fools that dare cross the waters without respects, for the Keeper of the Depths is always watching. He who was born in these waters and gave life to the Erraldoi and protects all form of life in the ocean. Khastu, the Fairsea, who is calm and chaotic, as the ocean that gave him a home, and who will punish those who dare disrespect it".
