unfinished thing i did once because. Ya’ll know the reference I hope.  
Yes she is huge, my headcanon is that magic needs space to be, that’s why the alicorns are big p. but the magic also goes into the hair, that’s why twi is still a small p in the default timeline.
 
lun and tia have come to kill her because she is a potential threat to all of existance, obviously they aren’t happy about it.
 
in this timeline twi summoned anon too early and didn’t have the power to save him from death yet, as time went on and she turned mad, celestia and luna knew that she would reshape the universe if she could but in her madness she would eventually just destroy all of life.
 
bad end
