Amidst all the work on Dangan Ronpa: Alternative, two of my friends and I got together to play a game of Dawn of Worlds. These are the avatars of my friend Nightmare and I.
The Prismatic Elemental is Etium. His bones are made of metal, his lifeblood is water, his wings are air, his skin earth, and his mind fire. However, in a rather silly event where he flew over a land form called The Eye of God, his earth skin crystallized.
The gelatinous being in the mask is Batall. He is simply described as a Gelatinous being who wears a mask. One day, when he and Etium were playing a game (in which Etium flew around the mountains of Tearus as fast as he could and rammed into Batall), Etium crashed into Batall too hard, breaking off some of his crystal skin into Batall. Now Batall looks like he does above.
These two are described as the DemiGods of Mayhem and mischief, as they are just childlike beings who want to have a lot of fun~!
