[@Lovejoy] I like the idea of needles for drawing ether.  Probably it's done a bit like dialysis, but requires an etheric component?

When I say fire I mean her ether manifests as fire -- just as it would manifest as force if I went with that one.  If you would prefer her not to be straight fire perhaps I could make it more...explosive?  That'd put it more toward force usage, but perhaps with the addition of a spark (I can make a gadget to produce them) she might be able to generate something flashy.

The down side of that, of course, is that because her power is geared towards explosions a lot of the simpler applications for ether would be beyond her.  If most priests can light candles with a though, her attempts would end up with wax everywhere, or a completely melted candle.  A small ether light would be a bright flash, etc.

Waitwait, backup.  I reread the bit about fire...are you saying that candles, flames, cookfires, those don't exist anymore?   You can't make a spark with flint and steel?  Things don't burn?  Or are you just saying fire as a form of magic is gone?  (Though wouldn't a bit of it remain in Omestrian ether?)
