My Monstrous World

On an afternoon of idleness and monotony, upon discovering a family heirloom, a portal to an unknown world opens before Noah.
Now encountering horrors out of nightmares, powers beyond his comprehension and a wound that eats away at his sanity, the young man will have to find the way to survive this, or if he can, fight it.
