The Extra-Stellar Loony Adventure of Characters Over Insanity's Limit by Thaumic Writer
Twilight plays Stellaris. She might go insane. I don't own MLP or Stellaris. Hasbro owns MLP and Paradox Interactive owns Stellaris. Don't expect seriousness of the SAME sort you normally get. Might get funny near the end, but only because of how ridiculous it will be while still (at least trying) to make sense and seem like it could be an actual episode. Weird, but possible.

New updates are featured in here, you'll know it coz it's obvious.
