A high desert of fused silica and standing prism-stones — flat in places, ridged in others, scattered with shard-fields that catch the sun and throw it back as colour. The Glass Expanse is the most visually unstable region in the Everloop: light bends here in ways the Pattern cannot quite hold, and the air itself sometimes refracts a scene from a different hour. Prism City is its capital and largest settlement; Clearline, Vell Glass, and Twinmark are its working towns. Echo Ruins predates the Weaving. The monster known as The Starving Silence is the regional Fray-consequence — born where light shattered the same way too many times in the same place. The Knowledge Fragmentation Principle was first formalised by Glass Expanse philosophers a generation before the Luminous Fold accepted it.
