She is now a milkmare, who takes up astronomy!
She is basically a bi.
Due to her discord eye, she can not only just make regular milk, but chocolate milk as well with will. Her eye was cut out when she was a filly, and replaced with a discord eye. Her breasts are also so big, they can fit 3 large dildos!
(I’ll give you a few guesses to figure out where her outfit came from.)
