Well, energy in the short-term at least isn't an issue. Earth offers much in terms of it, even if it's admittedly a bit... low-grade. *She doesn't MEAN that as an insult, but.*

But the "tool" is the issue, correct. Failnaught, and his type specifically, are the "tools" in this case. But he is the only one now who is still in a usable state, which has created the conundrum.

The closest one who existed before, of course, was Scythe, and even he wasn't exact-- his expertise lied in the ability to "remove".
