Hyperlane Corridor

A surveyed translation route between two points, held open by beacons and by traffic. Checkpoints and raiders gather where the traffic is, and a published schedule is a security risk.

Extraplanetary

Exposure

  • Vacuum

    No pressure and no air to breathe, with survival measured in rounds.

    • Countdown

      Without a seal, a creature holds out for a number of rounds equal to its Constitution modifier, minimum 1. At the end of that time its hit points drop to -1, unless they are already lower, and it is dying. It cannot be stabilized or regain hit points until it can breathe.

    • Decompressed

      Exposure inflicts the Decompressed condition, which a return to pressure does not by itself remove.

    • Holding your breath

      Holding a breath in vacuum ruptures the lungs. A creature that does so takes 2d6 damage on the first round and gains no benefit from the attempt.

    • Sound

      Sound does not travel. Verbal spell components, shouted orders and Perception by hearing all fail across open vacuum. Suit comms and touch are the only channels.

    • Unfiltered light

      Without air to filter it, the star's output arrives unreduced. An hour of unshielded exposure in direct sunlight counts as a failed Contaminated Atmosphere save against radiological dose.

  • Zero Gravity

    Free fall, where there is no down, no moving body stops on its own, and a missed handhold leaves a creature adrift.

    • Movement

      Moving requires a surface to push from. A creature with nothing in reach continues in the direction it last moved until it reaches something.

    • Changing course

      Changing direction mid-drift requires a DC 12 Dexterity (Acrobatics) check. On a failure the creature continues as it was.

    • Melee

      An unanchored melee attack has disadvantage and pushes the attacker 10 feet away from the target after it resolves.

    • No falling

      There is no up, no down and no falling damage. A creature cannot be knocked Prone, and the Prone condition does not apply.

    • Mag boots

      Magnetic boots or a tether remove every entry above while a ferrous surface is underfoot, at the cost of half movement.

In play

  • Travel roll

    A leg is a single Piloting check against the distance DC. The roll sets what the leg costs, and the leg always completes.

  • Predictable

    Traffic on a lane runs to a schedule that can be read from a dock manifest, and raids are planned from those manifests.

  • Checkpoints

    A lane through claimed space includes an inspection. Avoiding it means leaving the lane, and off-lane transit raises the DC by 4.
