It's time to make him my character officially. His name is Cayan and he accidentally have signed pact with some demons. Now he works as gate between two worlds. Read the terms and conditions of your contracts guys.
One eye seems to be blind but already is seeing weird things. Second eye is normal, but when demon want to pass the 'gate' it turns black.
