Controls

• Directional ▲ Wormsign shows approach bearing
• E at Sietch bay — unlock Ornithopter

Lore-informed systems

• Sandwalk: irregular, sliding gait to avoid rhythmic footsteps Shai-Hulud tracks
• Wormsign: rising sand / spray as the Maker approaches (books), not a CG worm body
• Rock / Sietch: safe — the Maker does not pursue onto stone
• Ornithopter: unlocked at Sietch Tabr for overflight
