Traumatized, distant, and lost in her own existence, Princess Luna teeters on the edge between herself and her demons. She evades the ones she loves to avoid her past. She can't possibly face the horrors her banishment brought upon her inner being. And so, resigned to her fate, that no one will consider her for her, she attempts to move on when she can only stand still.

Meanwhile, down below in Canterlot, Three Dee is a struggling pony who's luck has finally run out: when he is fired from his second job, and unable to make ends meet, he weasels his way into royal servitude to provide for himself. When he is personally recruited by Princess Luna for other duties, though, he identifies with her hidden plight, and there is only one thing he can do: listen, and perhaps provide some comfort in a world that is cruel.
