This document specifies the complete stage-by-stage design for Sector 1 of Tao Baryon — the player's first six stages. Each stage is defined by its identity, narrative role, wave timeline, enemy composition, named formations, difficulty calibration, rewards, and design intent.
For sector overview and difficulty context, see 03_difficulty_curve.md. For enemy specifications, see 07_enemies.md. For boss mechanics, see 08_bosses.md.
Sector name: The Frontier Stages: 1–6 Recommended Pilot Rank: 1 → 8 Difficulty score range: 1 → 8 Lore frame: The disputed border between human and Telos space. Years of front-line combat have left it a scarred no-man's-land of derelicts, debris, and patrol routes.
Visual theme: Conventional deep space, distant stars, occasional human or Telos beacons. Backgrounds darken and add debris as sector progresses, reflecting deeper penetration into Telos territory.
Audio theme: Subdued, tactical, military procedural. Sira-Vel's voice during intel briefings is calm and rehearsed early in the sector, growing more focused as the player nears Maelin.
Enemy roster active in Sector 1:
Boss: The Reverent Maelin (Stage 6)
| Field | Value |
|---|---|
| Stage number | 1 |
| Stage name | First Light |
| Sector | 1 — The Frontier |
| Position in arc | Sector intro |
| Recommended Pilot Rank | 1 |
| Difficulty score | 1 (lowest in the campaign) |
| Expected duration | ~3 minutes (slightly shorter than average — gentler intro) |
| Energy cost | 1 |
| First stage flag | Yes — triggers tutorial overlays |
The name First Light refers literally to a pilot's first authorized combat sortie, and figuratively to the dawn of the Frontier Commander's role in Operation Penumbra. It also signals what kind of stage this is: the beginning, the moment of transition from civilian to combatant.
This stage opens the entire game narratively. Two things must land in 5 seconds of intel briefing:
"Frontier Commander. Welcome to Operation Penumbra. You are launching from Coalition Station Achernar into Telos Sector Δ-7 — disputed space. Patrol elements only. Watch the formations. They mean something. — Sira-Vel out."
Total active gameplay: ~165 seconds (2:45).
0:00 — Stage loads. Player ship is centered, lower third of screen. Brief 1.5-second "approach" cinematic. Tutorial overlay #1:
"Drag left thumb to steer. Tap right button to fire. Hold for sustained fire (watch your heat)."
Auto-dismisses after 4 seconds OR when the player first touches the joystick.
0:05 — First enemy spawn: Single G1 Patrol Drone. Enters from top-center, drifts slowly down. Does not fire for ~2 seconds — gives the player time to react. Then fires a single Pulse shot at the player's general position (not predictive — easy to dodge).
0:08–0:25 — Two more G1 Patrol Drones spawn at staggered intervals (5 seconds apart), entering from slightly off-center positions. Same slow drift pattern.
0:25 — Tutorial overlay #2:
"Pickups are attracted to your ship. Collect them all."
A small pickup (credit cluster) drops at center-screen from a destroyed drone.
0:30 — Phase 1 ends. 3 enemies killed, ~30 credits collected.
0:30 — The Crescent (small variant) — first scripted liturgical formation. 4 G1 drones enter from top in a curved arc, moving down-and-outward in unison. They are visibly synchronized. They fire Pulse shots in a coordinated 1-2-3-4 sequence (left to right).
Codex entry 003 "The Crescent" unlocks on observing this formation for the first time.
0:50 — Procedural wave A — 3 enemies:
pool:
G1: 60%
G2: 30%
K1: 10%

"Heat builds with sustained fire. Pause to cool."

G2: 40%
K1: 10%

G1: 40%
G2: 50%
K1: 10%
spacing: 1.0 seconds2:00 — First special charge tutorial (if special is full):
"Special ability ready. Tap the special button to deploy."
2:15 — Phase 3 ends.
2:15 — The Closing Drone — single special G1 marked with a small white pulse marker. Killing it triggers a small audio cue (a brief Telos liturgical fragment, 1 second).
2:18 — Final scattered procedural wave of 3-4 G1 enemies that approach in disarray.
2:35 — Stage clear automatic when last enemy is destroyed. Clear screen appears.

The name Patrol Pattern refers to Telos standard sector-defense doctrine — coordinated patrol formations rotating through assigned space. Stage 2 is first real combat — the training wheels are off.
Sira-Vel's briefing is less ceremonial, more operational.
"Frontier Commander. Sector Δ-7 north grid. Telos patrol formation detected — standard sweep doctrine. Engage and clear. Note: kamikaze elements active in this grid. Stay mobile. — Sira-Vel out."
Total active gameplay: ~180 seconds (3:00).
0:00 — Stage loads. No tutorial overlay.
0:05 — First wave: 3 G1 Patrol Drones in a loose vertical line, descending at staggered intervals. Each fires a single Pulse shot at the player's position.

The name Sweep Theta is Coalition combat designation for the Telos formation type that dominates this stage. Stage 3 introduces Strafer enemies.
"Frontier Commander. Telos response forces engaging Coalition patrol routes. They've shifted to Sweep Theta doctrine — horizontal coverage formations. Strafer elements deployed. They're learning your patterns. Adapt. — Sira-Vel out."

A Coalition signal-intelligence outpost in the disputed border space — the Frontier Commander is deployed to defend it. First stage with a tactical purpose beyond "clear the patrol." First stage where intercepted Telos religious transmission plays in-game.
"Frontier Commander. Coalition Listening Post Δ-12 is under Telos attack. The post is recording valuable intercepts — defend it long enough for the data burst to complete. Estimated burst time: 4 minutes. They're sending heavier units this time. — Sira-Vel out."
The screen briefly tinges magenta. A voice fragment plays (text on screen, audio TBD) — a Telos prayer in their liturgical tongue. Translation appears below in white text:
"...we are children sleeping in a shallow dream... the dream must end..."
The transmission lasts about 5 seconds. Does not pause gameplay.
Total active gameplay: ~225 seconds (3:45).
0:00 — Stage loads. Listening Post visible at bottom-center. Small HP bar at top of screen. If post HP reaches zero, stage fails.
Tutorial overlay:
"Defend the Listening Post. Stage fails if post HP reaches zero."

First stage where players genuinely struggle. First Bomber (B1) appears here. Sustained density. No defense objective. The player must prove they can survive a hostile sky.
"Frontier Commander. Telos response forces escalating. Heavy bomber elements detected in your operational zone. Coalition Intelligence believes the Telos are protecting a high-value asset in this sector — possibly a regional commander. You're being deployed to disrupt. Expect resistance. — Sira-Vel out."
The mention of "a high-value asset — possibly a regional commander" foreshadows Maelin's reveal in Stage 6.
Total active gameplay: ~240 seconds (4:00).
0:00 — Stage loads. Background continues darkening trend — more debris, distant smoke, faint silhouettes of Telos installations far away.
0:05 — Opening wave: 4 G2 Pickets + 1 S1 Strafer.
0:15 — First B1 Telos Drop Bomber appears. Visibly larger than any enemy fought before. Tutorial overlay:
"Bombers drop area-of-effect payloads. Destroy them quickly."
B1 drops first payload at 0:20 — 3-5 slow Spread projectiles fanning outward.

3:00 — The Holy Patrol — final named formation. 2 S1 Strafers (high altitude) + 4 G2 Pickets (mid-altitude, in tight formation) + 1 B1 Bomber (descending behind). They move together as a single unit. They fire in synchronized pulses.
Codex entry 019 "The Holy Patrol" unlocks here.
3:30 — Final procedural wave — 5 enemies.
3:50 — The Closing Drone with much longer liturgical fragment this time — 5 seconds of continuous song. Not mournful — defiant.

After clear screen, before returning to Achernar Station:
"Frontier Commander — Coalition Intelligence has identified the regional commander. Designation: Reverent Maelin. Ace pilot. Personal kill marks number in the hundreds. He paints psalms on his hull — non-standard, even slightly heretical by Telos doctrine. The Veiled know him. They fear him. Tomorrow you launch against him. — Sira-Vel out."

Stage 6 is structurally different from Stages 1-5. The first ~2 minutes are escalating combat that funnels into the Maelin encounter. The boss fight itself is then ~90 seconds. Pre-boss waves serve as emotional and mechanical warmup.
Maelin boss spec already locked in 08_bosses.md.
"Frontier Commander. Operation target: Reverent Maelin. Telos ace pilot, regional commander of this sector. The Veiled have shared what they know. He has been flying these patrols for forty-three years. He has killed more Coalition pilots than any single Telos officer in our records. Coalition Intelligence has confirmed his current position. You are cleared to engage.
He paints psalms on his ship. He does not speak during combat. He has refused mercy and refused surrender, both offered and given. He is — by every Telos doctrine — not even properly orthodox.
Sira-Vel out. End the Reverent."
Total active gameplay: ~300 seconds (5:00).
0:00 — Stage loads. Background is darkest in Sector 1 — Telos installations visible in distance, debris clouds, smoke from recent battles.
0:02 — Opening assault — 4 G2 Pickets in tight wedge, immediately firing 2-shot bursts. No drift-in. No warning.
0:15 — The Holy Patrol (Variant 2) — 2 S1 Strafers + 4 G2 Pickets + 1 B1 Bomber.

spacing: 0.8 seconds0:45 — Phase 1 ends. Player should be at ~70-80% HP.
0:45 — The Reverent's Crescent — new named formation, Maelin's signature pre-engagement formation. 6 G2 Pickets in tight crescent, with 2 K1 Divers held in reserve at upper screen corners. K1s commit to dives only when player closes within mid-screen of the crescent.
This is a trap formation — designed to punish aggressive players.
1:15 — Procedural wave — 6 enemies, with one priority element: a B1 Bomber that drops payloads in a Mandala-like pattern (foreshadowing Sector 3+ bullet types). Codex entry 024 explains: Maelin has personally trained his patrol pilots in more advanced techniques.
1:40 — The Final Patrol — 3 S1 Strafers in synchronized triple-crossing + 2 B1 Bombers descending behind. Last wave before Maelin appears. Meant to drain the player slightly.
2:00 — Phase 2 ends. Brief 2-second pause in spawns. Screen quiets.
2:00 — All current enemies on screen are destroyed by an unseen force (brief sweeping light effect — Maelin's first shot, off-screen, clearing the path for himself). Screen briefly dims. Music transitions to Maelin's theme — quieter, more focused, almost mournful.
2:03 — Maelin's ship descends from the top of the screen, drifting slowly into view. Larger than any regular enemy. Hull visibly covered in painted psalms. Engine signature warm orange. He holds position at upper-center, not firing.
2:05 — Brief on-screen text:
Reverent Maelin Ace Pilot, 43 Years of Service Sector Δ-7 Regional Commander
2:08 — Screen shows: [NO TRANSMISSION RECEIVED]. First in-game characterization — Maelin is silent.
2:13 — Maelin's boss HP bar fades in. 3-segment bar showing phase boundaries.
