Here we have Grimnir. Brother to Mundilfare and future lover of Sindre. Grimnir is the King Under the Mountain, King of all Spirit kind in his part of the world. He protects them from humans.
Grimnir and his brother are Ice Giants (of Norse inspiration) and while Mundilfare is the pretty white and pure colour of newly fallen snow in a sunset, Grimnir is the dirty and dark snow after a battle or and avalanche.
Grimnir belong to me and my co-creator (http://hya-chan-art.tumblr.com/) to our upcoming webcomic called Numina Pyrite. Grimnir is one of the two protagonists together with Sindre.
