Take the tripod beside Mike’s hand. Look at the loose stone to plan the fulcrum, use the tripod on the lintel, free his boot, then climb to Portal Clearing.

Take the hollow reed and insect husk. Combine them into the Buzzing Whistle, then use it on the vine.

Use the Empty Ration Pouch on the Reekfruit plant.

Use the flashlight and toolkit on the hatch. Combine radio with toolkit, then wire with knife. Fit the stripped wire and retaining clip to the contacts. Compare Eleanor's notebook with the powered map.

Use the binoculars on the distant military road. Identify Earth at the powered relay first, then finish the chapter or keep exploring.

Use binoculars on the checkpoint; follow the east path into the Resonant Forest.

Use the empty ration pouch on the resin. Three portions are allocated; patching the fungus uses only one.

Take the loose crystal, use the knife on the shed shell, and use the canteen on the water. Combine the plate with the knife to cut an insulating washer.

In Inventory, Examine the radio and open its coil catch. Examine the flashlight and remove its battery. Combine coil + crystal with the battery in your pack. Use the field lure on the boulder. Release the root binding to revisit the lower forest.

Examine the radio and cut its reflective backing free. Use the knife on the fiber plant. Combine backing + fiber, then use the shiny lure on the low branch. Take the nest contents.

Use binoculars on the caravan. Look at the marker, then follow the steps south to Falling Water.

Use the conductor disc on the console. Rotate the terrain clockwise until the falls lie southeast and the split mountain north; verify the alignment. Inspect the signal and take the three-symbol device.

While snared, use the Ancient Tone Device on the stranger. Play the three symbols, introduce yourself, and follow her lead through the patrol scene. Prepare supplies before choosing to depart for Talar.

Engineering: visit Keru via Water Works. Animal care: north from Market. Language: south to Shrine. The elder needs pump repair and a partial translator.

Use screwdriver or toolkit on the heater. Combine mineral residue + root resin. Use the paste on the heater; Keru provides fiber. One paste portion remains for later.

Help Oren’s animal. Use the carved trade token or harness clasp on Varra, then confirm the trade with both in your pack. The later Talar pass is never spent.

Complete the calibrated pump and translator. Talk to Maera and explicitly begin the briefing. Follow its three pages; supplies arrive and the patrol begins only at its end.

Use the tone device on the console. Na=water, kir=fire, tal=person, esh=star, orr=animal, en=home. All six associations plus the traded wafer permit comparison and a partial translator.

After Maera’s briefing, Look at scanner. Examine radio to salvage its final signal wire. Combine coil + crystal with wire in pack. Use jammer on pipe. Ask trader for robe, use robe on alcove, then depart east. Sela recovers coil and crystal.

Observe the crew until they leave. Use toolkit on the truck, select manual cargo reset, then hide in the cargo crate.

Take the tag; use the translator on the alarm, then bridge its test contact with the toolkit.

Take the fragment. Use the toolkit on the classifier, fit the fragment, select BLUE and test the route.

Look at the relief and take the ceramic sleeve. Both matter before leaving.

Examine the fiber roll to cut bands. Combine them with the shard. Test the key on the lock, then use the remaining conductive paste on the lock.

Set TWO LONG TONES and WORKER GATE, queue the plan. Optionally queue local cells and unlatch the shortcut. Commit only when Ortega is free.

Use Sela’s signal whistle on the sheltered tunnel mouth, then take the dry east path.

Talk to Ortega through all four account pages, then agree on Kethara. The eastern trail reopens the completion summary.

Use tools to open the jobs. Clean the heater, swap middle/final timer gears and test, or use the measured local compound on the toy. After one job, borrow rigging, support the unloaded lift, reseat the cable and test. Buy speaker/cell and collect solvent from Narik.

Collect dry dust with the ration pouch. Go east to the relay bay. The south sector gate opens after the surveillance solution.

Use toolkit on the novelty device, free its stuck contact, then buy the recorder for 2 credits. Full price is 5; jobs pay 10 total.

Complete the badge and emitter branches in either order. Use the assembled emitter on the relay cabinet, then recover portable parts once the interior release has latched.

Ask the clerk through Sela about communications transfers, or select detention communications 7 on the conduit labels. Records and Drakel can be solved in either order.

Close central flow; open western bypass; set high pressure HALF; release central gate. Then choose detention communications 7 on the intake labels.

Stage all three samples at Control and confirm evacuation. Ask Reed to analyze timing at the terminal, select Sector Four and paired pulse timing, then transmit. Use the east escape.

Use coil on heat probe with the recovered city cell; dust pouch on particle intake; Narik’s solvent on chemical grille. Review and trigger evacuation. Recovered recorder/translator must be packed for Reed.

Talk to Reed through five saved pages. Optionally visit Narik via south and return the badge. Take the north stair and confirm departure for the observatory.

Talk to Reed and accept preparations before climbing north. After escape, hear all reunion pages and take the south road.

Set large moon NW, small moon SE, bright planet NE; test the optical channels. Wrong trials reset harmlessly.

Select LEFT, move weight to left cradle; select CEILING and latch upper cradle; select RIGHT and release return ladder. During lockdown select third track, then feed the weight into it.

Go east to Upper Lens Gallery. An optional stair latch there gives access to lower lenses. Return west down the ordinary gravity ladder when needed.

Use the latch to open the central stair if desired. Earth alignment from below and restored gravity access allow the eastern archive door.

Use toolkit on shutter; pull dust release; use Sela’s water tube on intake; take and use probe on touch sensor. Review guard-only boundary, trigger preservation, then talk to Eleanor.

Use translator on records and data wafer on socket. Order: roads opened, keepers assigned, breach detected, sever network, keys separated, guard sleeping gates. Read all pages and preserve copies.

Release a lens and shift weight into the telescope track in either order. Ask Eleanor for WEST / TWO, select it on controls, rotate, use fiber then sling on anchor, tension-test and traverse.

Solve gravity and Earth alignment in either order. After records are copied, examine the network account and review withdrawal at the promenade console.

Ask Eleanor, set NEXUS, use translator on recesses, use recorder and test raw pulse, then route it THROUGH TRANSLATOR and test. Nothing is consumed.

Take the east opening; the central rubble is impassable.

Take markers. Use white and blue on conduit; ask Eleanor for its protected-system glyph, then assign task. After diagnosis, verify mobility cell and detach the separate reservoir at charger.

Switch Security off and Wayfinder on; apply. Optional latch opens shortcut. After diagnosis, recover charger reservoir and use it on isolated cradle. Leave its discharge isolated.

Use diagnostic after discovery. Build reference at Calibration and connect isolated reservoir at Ring in either order. Release fail-safe lever and stage device/team before starting handoff.

After diagnosis, collect coupling lock; connect oscillator, recorded feedback and gel/coil. Choose IRREGULAR heater, test live reference and pack it. Both reserve/reference orders work.

Use variable reference on interface. Stage team and fail-safe; start prepared handoff. Feed recording, add variable circuit, read glyph, release first and second sensors, ease third, STOP and retune, then remove harness. Unsafe order restores prepared checkpoint.

Ask Eleanor for closed calibration address, Mercer for +1 phase / 3-beat delay, Reed to prepare reply. Use toolkit on couplings, then mechanical lock. Set INTERNAL address, +1 phase, 3 beats; send reply.

Use red marker on failed sensor. The custodian holds it while both pressure doors synchronize. Leave south; it stays inside.

Talk to Sela or use camp route, read all reunion pages, then leave east and commit to the fortress approach.

Follow the dry eastern promenade to the lift. The watercourse is not a shortcut.

Use the fresh sensor strip from the reservoir locker on landing sensor, then request shaft inspection. Take the lift upward.

Take service supplies/communicator and read inscription. Visit relay for false orders and overlook for reconnaissance, in either order. Orders open prisoner access; Briggs and reconnaissance are both needed for Delaney.

Read old sign at Service Quarter; take communicator there. Use retained recorder on relay, intercept shift code, choose OLD / MODERN AMBIGUOUS, record Sela, transmit. Exact modern and emergency versions are rejected safely.

Use gauges: read evacuation exception, map four reports with Reed, record reconnaissance. Lower access still needs false orders. Delaney rescue additionally needs Briggs.

After Briggs rescue and recon, use toolkit on service controls. Ask Briggs to map, hold reports, move first and second carts east, release opposite counterweight, restore reports. Speak to Delaney and finish all account pages.

Finish both report pages and copy ARRIVAL VALLEY. Use rendezvous to recall Reed, Mercer and Ortega. Reed leaves a dormant overload relay and brings the local trigger; all eight must be here before Key recovery.

Key: select ARRIVAL VALLEY, isolate modern monitor, set vanes 1 / 2 / 3, compare, take/use service bar on cradle, turn twice, recover after team rendezvous. Confrontation: exposure then boundary; use bar and Key on selector; choose ring 2; stage Delaney/Briggs; save/start, trigger dropout, redirect bus, seal. No hidden timer.

Use bulkhead lever, confirm all eight, close it. Optionally contact Sela’s allies for eligible help. Leave east; no mandatory item comes only from an ally.

Finish the three reunion pages, prepare road home, take the east path and explicitly leave for portal valley. The ending saves; choose Continue to Chapter 9 to carry the expedition onward.

Use relay, read custodian access; stones: loose cap, left wedge, right chock. Never remove the loaded arch.

Trace OUTER BARRIER, record telemetry, wind local dummy load, build suspension. After cradle prep: stage bypass, loop, engage load, extract, lower stand, isolate feed. Fit core; patch conduit; jack, align index to 2, lower load.

Origin: inward. Sky: 180-degree viewpoint turn (not mirror). Compare watch: B, controls 2/1/0. Verify each, then explicitly commit VERIFIED PAIR ONLY / NETWORK SILENT and review departure.

Talk through Veyr confrontation. Prepare crisis checkpoint. Invert carrier; set amplitude 2; commands UNVERIFIED SOURCE, REFUSE HANDSHAKE, RESTORE VERIFIED PAIR. Release both supports, send Sela. Disconnect, rotate, brace with service bar, reconnect first then second. After stand-down open Earth, send six in order, return pass, remove Key and cross last.

Speak to the expedition. The west door advances several hours to the debrief.

Complete the two briefing pages. Conversations are optional; Finish the debrief commits Key transfer and begins the midnight epilogue.

Continue the final illustrated sequence to the end title.
