They could just keep that, or the obvious parallel with XII which would be the Necrohol of Nabudis. However, that’s not a very notable location.
How it is not? It's a huge part of FF12's backstory, even if in actual gameplay it ended up being an optional area (one that the game more or less explicitly tells you is highly dangerous)

Loads of characters in the game refer to Nabudis (usually in a context of warning, like Reddas's "do not forget Nabudis") as a representation of the dangers of mankind's hubris with regard to nethicite, nethicite being more or less the game's allegory to RL nuclear power.
