Long ago, secret occult built a portal to another dimension! After some period of time, when they finally managed to make it work, something disastrous happened! Gate to other dimensions or realities changed it self. By all means gate tried to negate two dimensions but at the end it grow into something different than it was ment to be... :P

Point of interest is the portal, rest is just a background, that's why entire build is not shown.

Have fun and productive day!
