The Iris

The Iris is the main focus of Gemini Home Entertainment. Little is known about it other than its hostility towards Earth, and its 5 moons.

As revealed in the tape about our solar system, it orbits just behind Neptune, which has somehow been corrupted by its influence.

It was visited by the crusader probe in 1993, which took several photographs of its moons, and some of the empty space around it (full tape viewable here).

It is possibly the origin of woodcrawlers, nature's mockery, and perhaps skinwalkers; by either sending them back with the probe, or by influencing Mariana's Trench.

In the ending of Lethal Omen, the Iris visits the Earth directly, and presumably consumes or destroys it.
