Eve of the Feast
Golden Age Arc III
The Interstice is a blended space between the physical realm and the astral plane from which creatures spawned from the subconscious will of humans and deceased spirits reside. Compared to normal humans who would have a firm hold on their plane of existence, certain humans that use magic (like witches and wizards) or those branded with a Brand of Sacrifice (like Guts and Casca) have a footing in the Interstice and can interact with the beings residing there. The Skull Knight also possesses the ability to exist between the two realms.
Such examples of Interstices would include the realm where the Eclipse occurred, the domain in which the Mansion of the Spirit Tree is found, and a forest cave near Enoch Village where Slan situated her nightmarish astral realm of Qliphoth. The World Transformation ushered in by Femto causes the merging of the physical and astral worlds, thus creating a global Interstice.
