Gerson's crabapple garden has been long boarded up, and remains one of the few untainted places in the entire Underground, protected by ancient magicks and the will of the old tortoise monster himelf, his dust spreading across the roots of the enormous trees and lingering around his abandoned shell, explorer's helmet, and battleaxe. The apples grow still, strong and large and juicy under the crystal lights in the cavern ceiling, fed by the drip of untainted water from the large lake on the surface.

It could be solace for anyone that finds their way in there.
