Weeks of spelunking eventually led you to this little isolated place. A carved metropolis seemingly powered by Aura energy. Runes and erected monuments serving as a silent testament to a society long since abandoned, but despite the age of the place, you see that the underground urban stone haven hasn't suffered any noticeable wear or damage. That is because I stand here as its steward, keeping vigil over it. The concentrated aura that has gathered here through generations of accumulated lives is a source of power that some may seek to wield for their own destructive goals. But it also gives me the extra strength to seek my goal of ensuring no such creature will leave here with it.
