Nethus, the God of the Nether Dimension.

Nethus in Minecraft Mytholology was once a great hero who was known to dwell in the nether having a particular affiliation with lava, one day while exploring in the Nether, an infected Netherrack block infected him and slowly converted his body, Ovaedus, his brother who had already ascended to godhood, granted him god powers.

Ovaedus's only rule was "You may not interfere with the mortals in any way", this rule he abides by out of a moral obligation as thanks rto his brother for giving him a chance to "Live on"
