The princess was stuck in Equestria with attempts to handle growing tensions within the realm (attempts being the key word, it seemed anything Luna did to help just made things worse, but Celestia was becoming more and more agitated about her long absences, and Luna was in no mood to be thrown back into any form of prison).
Frustrated a bored, she played with the shadows, forming them to her liking, and finally decided on the shape of a raven, which she imbued with her magic. With a moment’s pause to pet the whispy feathers, she sent the shadow raven off, where it dipped into the cracks of the realms.
It’s journey ended outside a window that Loki was near. It perched, twisted its head this way and that to peer in with its bright blue eyes, then pecked at the glass.
