Hati Hróðvitnisson

Son of the moon - abilities deal with ice, cold, and darkness - can only be outside during the night time - sunset to sunrise. He starts off literally not being able to be awake during daylight hours, passing out at sunrise and waking at sunset, but as he grows and gains power, he's able to stave that off. Hunted by Synotra's descendants/assassin that originally had gone after Loki and Sigyn maybe?? Is known as sort of a deity/demigod with nothing but ill intentions and there is a festival held every year just for the sake of hunting him and his sibling. The teardrop gems on his face are said to have been the first tears he shed, and now he roams the world, fleeing from those who believe in the legend that his tears turn to diamonds in the moonlight.
