Mariel
The Mariel (mɑː.riːel) were created by Maris, the Goddess of Water, and were granted the souls of Undine which transfers mastery over the element of water. They are a combination of human and fish that seems to defy the laws of nature. Their populations are scattered in city states across the sea floors of Aserra’s temperate and tropical oceans. For a single year of their long lives, they undergo a transformation that allows them to live on land and reconnect with their cousins, the other elemental races.
