Ashfall

Cora Rayne is one of the scientists employed by Deiparous in their partly underground facility (legally belonging to Mount Isa). She's been with the company for a little over a month, meaning she's still doing grunt work, but she does it enthusiastically, accruing overtime despite there being no pressing need for it.

The cause of this mysterious behaviour is easy enough to figure out, of course: She strongly identifies with her job.

She's single, but aromantic.
