The Land of Caves and Silence, abbreviated as LOCAS, is Equius Zahhak's planet in The Medium. The planet is a shadowy desert wasteland with a network of blue-tinted caves, some of which contain waterfalls. Equius's hive is transported to the Medium as it is falling when the mesa upon which it is seated crumbles. His gate and his hive are likewise tilted in LOCAS. A really HUGE underling is near his hive.
After Equius enters the planet he quickly STRONGjumps to the second gate and enters the Land of Quartz and Melody, abandoning his own land almost immediately.
Interestingly, there is a E%ecutor Darkleer's .in LOCAS that highly resembles
LOCAS was destroyed with the other eleven planets when Jack Noir rampaged through the troll session.
