Use this table during intra-system travel or short interstellar legs in the Cradle. Roll once per travel day (or once per hex/jump leg on longer voyages) to generate potential encounters. All results tie directly into existing NOVACore mechanics: ship profiles, opposed Piloting/Gunnery Action Rolls, boarding rules, Party Challenge Rating (PCR) scaling, Salvage/Fabricate Action Rolls, radiation/toxin Health Action Rolls, and core sensor ranges.Travel & Detection Notes (Core Rules)

  • Standard Sensor Range: 2–4 AU (from core ship profiles). Upgraded Sensor Array module adds +1 AU.
  • Close Detection (<0.5 AU): Full scan possible (Recon Action Roll TN 12).
  • Distant Blip (>2 AU): Only vague readings (mass signature, velocity vector; no detailed info).
  • Farthest Fringe / Outer-System Edge: Possible “Outsider” sighting (see #20). Ships move too fast for pursuit or boarding—readings fade in 1d6 minutes. No combat possible; only sensor data or plot hook.
  • Corporate Raiders: Often bear old pirate-era marks (scarred hulls, jury-rigged weapons, faded Jolly Roger variants or corporate logos over black-market patches).

Frequency Guidelines

  • Core worlds: Roll once every 3–5 days of travel (low traffic, high patrols).
  • Fringe / asteroid belts: Roll once per day or per hex (high risk, frequent wrecks/raiders).

d20 Random Space Encounters Table
Roll d20 once per travel segment. Adjust frequency by region.

d20EncounterDescription & HooksThreat Level (PCR Add)Resolution Options
1–3Derelict Wreck / Abandoned PodCold ship drifting (roll on Random Loot / Salvage Tables). Possible radiation (RSR check) or automated distress beacon.None (0)Salvage Action Roll TN 12–18; hazard rolls (radiation/toxins TN 12).

6–7Mining Barge / Prospector ConvoySlow asteroid miners with escorts. May need help (repair TN 15) or sell fuel/parts.Low (1)Aid for favor; robbery risk if greedy.
8–9Generic Military Patrol (Luyten Empire / Directorate)Scout Frigate or 2× Gunboats scanning traffic. Routine ID check (Deception/Streetwise TN 15 to avoid boarding).Medium (2–4)Comply, bribe (500–2,000 oz), flee (opposed Piloting), or fight.
10–11Corporate Raider (ex-Pirate Holdouts)Light Frigate or Assault Lander with old pirate scars + corporate logo. Demands “toll” or cargo scan.Medium (3–5)Pay up (1–5k oz), bluff (Intimidate TN 18), combat, or outrun.
12–13Rival Pirate Crew (small raider band)Stealth Corvette or Drop Ship ambush. “Stand and deliver” hails.Veteran (4–8)Negotiate share, board them, flee, or full fight.
14Distress Call / Escape Pod ClusterDamaged ship broadcasting SOS. Survivors may be injured, trapped, or a trap (ambush on arrival).Variable (0–6)Rescue (Medicine AR), loot pods, or cautious approach.
15Space Hazard / Debris FieldMeteor swarm or old battle wreckage. Piloting AR TN 15–21 to navigate safely (failure: 2d6–5d6 damage).Hazard (0)Avoid or salvage scrap (Salvage TN 15).
16Smuggler Convoy / Black-Market MeetStealthy haulers exchanging cargo in deep space. May invite to trade (Broker TN 12).Low (1–2)Buy rare gear (cyber, modules at –10–20%), join deal, or raid.
17Automated Defense Drone SwarmOld corporate or military sentry drones activate on approach.Medium (3)Hack (Computer TN 18), destroy (Gunnery), or evade.
18Strange Anomaly / Sensor GhostFlickering readings (possible psionic artifact or “Cradle horror”). Navigation AR TN 18 to investigate safely.Plot (0)Gain rumor/hook; risk Strain if psionic crew.
19Fleet Movement / Convoy EscortLarge corporate or military convoy (Heavy Freighter + escorts). Hard to approach without detection.High (if hostile)Shadow for intel, attempt piracy (very hard), or steer clear.
20Outsider Sighting (Fringe Only)Distant, unidentified ship signature on extreme edge readings. Moves at impossible velocity; no pursuit possible. Vanishes quickly.None (0)Log data (Recon TN 15); plot seed for “unknown horrors” campaign arc. No boarding or combat.

GM Quick Tips

  • Frequency: Core worlds = roll once every 3–5 days of travel. Fringe/asteroid belts = once per day or per hex.
  • Scaling: Add +1–2 PCR per extra ship in group (e.g., pirate flotilla = +6–10 total).
  • Complication Roll (optional d6 after encounter):
    • 1 = Trap/Ambush
    • 2 = Distress is fake
    • 3 = Authorities incoming
    • 4 = Radiation leak
    • 5 = Cargo valuable but cursed (psionic trigger)
    • 6 = Friendly NPC offers alliance/quest
  • Outsider Flavor: Readings show sleek, non-human geometry; velocity defies known engines. No response to hails. Perfect seed for escalating “Cradle horrors” storyline.
