So here's what I came up with, TheEvilOcQueen! If you're unhappy with the selection, let me know, and I'll try to eke out a few more decent titles.

- Ashen Orphan (probably too straightforward? I dunno, it was my first thought after I read your summary)

- Death Among the Cinders 

- Maniacal 

- Descent of Grey 

- Grey Madness 

...not my best work, I admit, but like I said, I can give this another shot if you'd prefer!

UPDATE: Second Attempt 

- Breath of Ash/Cinders 

- Orphan's Decay/Orphan's Undoing

- Reaper's Lament 

- The Fall of Tragedy 

These might not be any better, but, well, I tried? So sorry if it's not to your liking!
