The Expanse's western outpost, positioned where the crystal desert borders the open terrain leading toward the Luminous Fold. West Mirror Post monitors the border and reports on the growing geometric patterns that seem to encroach from the Fold's side — crystal arrangements that are too regular to be natural. Out in the Glass Expanse, this site is part of the network of prism-fields, shard-towns, and silica plateaus that surround Prism City. Light bends here in ways the Pattern cannot quite hold — the air sometimes refracts a scene from a different hour, and the Starving Silence forms where light has shattered the same way too many times in the same place. The Knowledge Fragmentation Principle was first formalised by Expanse philosophers a generation before the Luminous Fold accepted it.
