House of the Moon

'I drift down sleep's familiar pathways, until the Wood comes clear before me with its grasping trees and shadow-fringed paths. But this is not the Wood I know. It is all birch trees, white as moonlight, and the moonlight is black as ink. Beneath its pressure, the white skins of the trees begin to blister, then bleed…'
'Without the Walls'

The House of the Moon is a mysterious mirror realm to the House of the Sun. Little is known about how it came to be, or what its purpose really is. It appears to be governed by the Meniscate, who once was a Name of the Sun-in-Splendour and served as his "night-self".

Perhaps the most curious piece of information regarding the House of the Moon is that the Wheel, one of the old gods-from-stone destroyed in the Lithomachy, is said to still turn, and some claim that the Wheel shall return someday. What this could mean for the Mansus is still to be revealed.

The Summit Gate

'My skin is tattering now. The Well is ahead, but the moon is changing, is black, is gold, is pearl. The blood of the Well is a red mirror, and three of them rise, and their faces are mine, are horned like the Moon, the greatest holds a key of black sapphire and when it parts my skin my body is rent like lightning, and WHAT IS WITHIN, WITHOUT, WHAT IS WITHOUT, WITHIN –'
'Three'

The only known way of entering the House of the Moon is with the use of the Key of David when housed in Black Sapphire to open the Summit Gate. The Key is held by Morgen the Ligeian, though it has been known to flee her many times.

The Summit Gate can be seen opening in Cultist Simulator only twice. Pursuing the Change Ascension of the Dancer Legacy with a balance between the aspects of Moth and Heart, "change and eternity", the player may gain the favor of the Meniscate herself, who will grant passage through the Summit Gate—not as a Long, but as a reflection, with the promise to return when the Sun-in-Splendour is reborn.

The other example presented is in the Exile Legacy, where the player may encounter Morgen. In the process of offering her pentiments for the Nameless Name, Morgen will recognize the Exile as "blood of the earth", the line of the Wheel and the Flint, and grant them passage into the House of the Moon.

Other Notes

• In addition to the Meniscate, who governs the House of the Moon, and the Wheel who turns within, there are a few other Hours that may have a connection to the hidden realm:
  • The Flint, who is mentioned alongside the Wheel with the Antaean line.
  • The Velvet, who appears to have a connection to the Wheel and to Morgen through her Nameless Name.
  • The Twins, who are alluded to briefly in the Balance ending of the Change ascension.
