Spoilers: the long lost friend was Princess Luna. ;)
I had this concept idea in mind that after trying to find her long lost friend in the forest for a very long time, she starts to loose herself with time. Becoming more and more attached to the land on till soon she may never leave it, and as she gets more and more attached she looses pieces of who she is on till there is nothing left but this insane spirit roaming around.
The insanity comes from the lack of rest from her constant search for her friend.
Well, this was my idea on her while doing this piece of work :3
ENJOY!
