Princess Stella
This is a character my friend made up a while ago. (If this is an actual fan character, I literally did NOT know!!!!)

So, Stella is the third Alicorn sister. She was born during a rebellion, so her first few years were out of the spotlight. When the rebellion was over, she stayed in the country. She lives in the depths of a branch of the Crystal Mountains, in a little valley that is located in a small hotpocket, keeping much warmer than the arctic around it.

In the valley, a village rests on the edge of a lake. The village is occupied by bat ponies, all of whom know who Stella is.

When Luna was possesed by the nightmare powers and banished to the moon, Stella visited her, taking messages from Celestia and keeping the goodness inside alive.
