A relay station built around a natural pillar of reflective crystal that serves as both landmark and signal tower. Mirror Post bounces light messages between Shard Camp and Glass Reach, and maintains the only reliable cistern between the deep Expanse and the settled eastern edge. 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.
