The Outsider

The Outsider originates in the game Dishonored, a joint effort by the studios Arcane and Bethesda. The Outsider is a god, not explicitly one of many or the only one, but he is not part of a pantheon. The Outsiders interactions with mortals extend no further than observing what he finds interesting, visiting people in dreams, and gifting mortals with his mark. Mortals he has marked gain supernatural abilities which vary. Examples range from running slightly faster to stopping time or possessing another person.

Those who have exposure to The Outsider or artifacts from his realm "The Void," become insane. The only exception is mortals who bear his mark.

Corteno is a character in The Cold War who bears the mark of the outsider.

The Outsider does not take sides or make demands, nor does he care what those with his mark use their powers for, so long as it is "Interesting."
