Adam supposed that at the Lower Ring, there was something that allowed this place to exist. The importance and value of the Cave Grid were beyond his expectations, but he wasn't going to delve into how the Citadel's economy worked.

"I see... The Cave Grid is the main source of the usual non-energy-infused materials, though if you go down deep enough you can find all the same stuff as at the Dead Lands, right?"

There are no monsters at the highest levels within the Lower Ring, but there aren't many energy-infused materials at all, or rather they're already gone too. All the rarest materials have already been mined."
"Tell me more about it," Adam asked quietly, watching the two trucks pull in from the east side, the White Tigers' territory.
