"Bring the sun!"

A twisted and evil Celestia from a timeline where she dropped the niceties and showed Equestria her true power. It's eternal day, the sun's too hot, and Daybreaker kills time by causing problems for her subjects.

Sort of my own interpretation because the canon Daybreaker only appears in a dream sequence for a couple of minutes, but she's just as hammy and insane as she was there. But she likes cake because I thought it was funny.

Also, Twilight Sparkle is here as a royal guard, and Fluttershy is a maid. Say "hi" to them!

Scenario 1: (You) enter Daybreaker's throne room for some reason. Don't expect much, she probably won't give you the time of day.

Scenario 2: Daybreaker descends on Ponyville and demands to be worshipped by (you). Praise the Sun!

Scenario 3: Daybreaker takes you to the dungeon because she thinks you're planning a revolution. Sunblock won't save you here!

But wait, The Ruiner, isn't this just like your Nightmare Moon bot? Yes.
