251–450m - Repair the Power Plant

Objectives

1. Upgrade equipment (depth module installed).
2. Scan Feedback Resonators → craft upgraded resonator (handles armored bloom cankers).
3. Gather Conduit Crystals.
4. Clear the Alien Ruins Angel Comb (Karakorum Power Plant, ~1760m ENE, 425m deep). Three juvenile combs (2 cankers each) + 2 final armored cankers. → Axum Vision Adaptation.
5. Lower Turbine Control Room (SE cliff, ~400m): activate panels → heat pipe lowers.
6. Scan damaged Turbine (~5m in front of upper control room at 200m).
7. Repair Turbine materials: 10× Titanium Ingot + 10× Mangalloy Ingot + 10× Strontium (requires 60× Titanium + 20× Celestine + 10× Atacamite + 10× Troilite at the Processor). Troilite is the scarce one — keep one seed for Metal Farm.
8. Build the turbine with Habitat Builder at the structure.
9. Upper Control Room: rotate symbol dials to align with yellow notches → glow green → activate central console.
10. Power Plant restored → Observatory entrance unlocks.
