This is not fair. This is not right. If the universe were fair then she would not be here. She doesn't deserve it. No one does. Death is a mercy compared to this. If she had her way, all of the Mists would burn and the space between worlds would be gone. This is stupid, and would probably break all of reality, but 'wandering in the Mists' is a torment that should not occur to anyone. Especially not to her.
Fortunately for her, spite is quite the motivator.
As she figures out relatively (as things in the Mist go, anyway) quickly, the necromancer from the first looping echo wasn't lying. Or false. Every time she finds someone she can question about Orr, they're either from the far distant past, or they agree with him. The charr invaded Orr, and Orr blew itself up. Her parents, having lived in Arah, are almost certainly dead. No resurrections, either, what with there being too many people for anyone to possibly sort through in the window available for a resurrection. They died never knowing what happened to her. They probably still don't, and they wait for her still in the Underworld. Everyone she ever knew and ever loved is dead. It's just her, alone in the Mists.
Well, all right then.
Her regrets get discarded like the rubbish that they are. She no longer has the patience for them. So what, if she wasn't quick-thinking enough to avert or avoid the disaster that got her here in the first place? She has not lost. Not yet. So what, if she doesn't know the way out of the Mists? She has forever. She will find it. So what, if everyone else that she meets is either not a person or crazy? She isn't. Not yet. Her loved ones do not know where she is and must think the worst possible fate has occurred to her, and in a way it has. But in another way, it hasn't, because the worst possible fate is the one she's running from. Despair. Hope is a bitter pill to swallow, but she takes it with every stubborn footstep, every comforting echo she turns away from. Maybe she's chasing a fool's errand, maybe it's impossible, but at least that's better than never having tried at all. Step (She will get out), step (She will get out), step (She will get out).
This horrible place may not have her. It will not take her sanity, and it will not take her will, and without those it will never get her.
She talks to echoes. When the echoes allow for it, she assists different sides in their conflicts just because she can. Because she enjoys it, and nothing else. There doesn't need to be another reason. She learns and theorizes and watches history play out through a thousand broken mirrors, and she keeps on living with herself. Maybe the things she has learned will never get used, maybe they'll die with her, but then she'll arrive at the Underworld and have so much to show for it. Or maybe she won't, and all she'll ever have is the knowledge that she fought. Maybe that's enough. She steals laughter and wit and fun from this damnable place. She is—beautiful. Terrifying. A creature that has walked through the Mists and will come out sane. She is not so arrogant to think that her mental fortitude is infinite, but it doesn't need to be. It just needs to last long enough to get lucky. Just once. Or maybe it's really a thousand times, but what does she care? She has forever, which in practice means 'until her sanity gives out.'
Her sanity takes a very long time to give out. Or maybe it doesn't. Maybe her flavor of insanity is 'I will do the impossible.' To be honest, she's fine with that.
She walks on.
