The Thirdspace Aliens are the unnamed dominant species native to the third known spatial realm, beyond both normal space and hyperspace. They believe themselves superior to all other lifeforms, and aim to destroy all life that is not their own. An extremely ancient and highly hostile species, these non-humanoid telepaths have exterminated thousands of species from their native dimension and will not think twice about doing the same on the other realms if they have the opportunity. Fortunately, a gate must be opened on both realms to allow their passage.
