Eraticate
Not sure how well a rat pun will translate into other languages though.
I don’t have a cool lore quip… words hard. Why can’t we have numbers instead…?
Oh what if the lore description contains the dates of each of the human civilisations’ downfalls/dates they joined the Last Refuge?
Huzzah! Numbers!
Wizard’s Pointy Rat
Trying to follow the rat-puns footsteps (admittedly, rather weakly).
(The) Last Stand
In our desperation to defeat the void, we became what we fought so hard against
Infernal Emptiness
“Creating something out of nothing Isn’t out of the ordinary for an Elder in his prime, but the source of this nothing was not ordinary”
Last Resort (or something along those lines)
"Reasoning that the void could not take what had been reduced to ash, some people razed their homes.
But the void does not reason."
