Dark Moon
The Dark Moon is a location below the first Temple of the Art layer in the repeating layers of The Work (Hell). Similarly to its counterpart in the sky, it's made of cheese, although this one has a darker, reddish appearance. Unlike its cousin, only a part of it is solid, making jagged cliffs with blood pooling in the space between them.
In the center of the Dark Moon, glyphs can be found that read "WHAT HATCHED".
Events
Similarly to the Moon, you can trigger unique events with similar requirements. Along with that, completing any event will award their corresponding Achievement Pillars.
The Blood Moon
If the Essences of Air, Fire, Earth and Water are brought to the center of the Dark Moon, the entire Moon will transform into Blood and this message will appear: "From my blood..."From my blood... From my blood... From my blood... From my blood...
Heretic!
Throwing a Refreshing Gourd at Kolmisilmä will deform its body into a gourd-like shape and turn it green.
Bringing the transformed Final Boss to the Dark Moon along with the elemental Essences (you have to be in the center of the Moon) will transform the Moon into acid and spawn 10 Kolmisilman Katyri with 2,250
instead of the usual 800.
The gods will be enraged, and this message will be shown: Heretic!How dare you do this!
Coordinates
The Dark Moon is found at x = 9 and y = 37513. As is the case with the normal Moon, Parallel Worlds have no Dark Moon, though it is also present in New Game Plus cycles (unless worldgen overwrites it for the cycle), permitting multiple Moon events to be completed within a single run.
