[Warning Spoilers] Twilight's Nightmare Art

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

Twilight Sparkle has spent months researching chaos magic, developing a new spell to unlock magic nopony has ever experienced before. But when something goes wrong with casting, Twilight finds herself turned into a Draconequus and unable to control her new chaos magic. If she ever wants to be a pony again, there is only one who can help her learn to control her new magic.

Of course, learning from Discord was never going to be simple. And after a while, being a draconequus doesn't seem so bad anyway....

Based on the concept by Lopoddity
