The Dark Sage

Mattheo, the dark sage of another world, is by his own request, sent to another world to undergo transformation at the hands of a dark god. What he wants precisely is the ability to ascend, by becoming a demon he can do that. Will this dark sage be able to survive in a world where the light shines brightest, or will he perish? Unfortunately there won't be daily chapters until my schedule loosens up, sorry. :/ I also plan on writing multiple stories in the same "universe", so look forward to it after a good long while.
