Collarbone Hollow

One of the Citadels is located in the western part of the Collarbone Hollow, near the Song Army war camp.^[2]

It is situated upon a tall and strangely shaped hill, distinguished by its dark and barren slopes. The hill occasionally produces ripples that spread across the shallow waters toward the jungle's edge, as if an enormous creature were breathing beneath the surface, its breaths reverberating through ancient bones.^[1]

This Citadel is guarded by a Great Demon.^[1]

The West Collarbone Plain is described as the last bastion of the Song Army in Godgrave.^[3] It can be accessed through two main routes originating from the Breastbone Reach, an area under the control of the King of Swords:

• The Greater Stronghold, located along the northern route, directly connects the titanic breastbone to the right collarbone of the dead deity.^[3]
• The Lesser Stronghold, located along the southern route, passes through the right first rib and served as Sunny's station during the events of Chapter 2081.^[3]

These routes serve as critical access points and defensive positions, reinforcing the strategic importance of the West Collarbone Plain within the broader conflict in Godgrave.^[3]

• In Chapters 2769-2771, Cassie witness the past of Godgrave or of the Sun Realm. Mictlan was the civilization born there in the wake of the Doom War called the Hollows.^[4]
