Each material ties into your **faction logic and biome placement**, allowing players to:

* Scavenge based on risk/reward (e.g., Titan Alloy in hostile zones)
* Craft gear with lore-driven properties (e.g., Aurōmy Timber for obedience-linked upgrades)
* Unlock environmental storytelling (e.g., Echo Shale whispering past battles)
