Lloigor
From Tardis Wiki, the free Doctor Who reference
The Lloigor were a group of Old Ones. They were not native to the universe, but one (the Animus) was able to get into it. Despite this, the amount of the effort and energy spent on doing this meant that the others would be unlikely to try the same thing. (MA: The Dark Path)
- The Lloigor may have been native to Calabi-Yau Space.
