RTF is a global modification that replaces all towns in the game.

I like Demilich the most. It’s short and clear.

Yes, that’s true, but then you also need to name the upgrades, like Ancient Demilich and Putrid Demilich. The word “Demilich” in combination with these feels a bit awkward to me, but yes, it’s one of the best options, and I might use it, and then replace it if I find something better.

“Deathlock” seems good, but it’s also a Marvel superhero, so that’s also questionable.
