  • A system with a wormhole is not an anomaly.

  • If a system contains multiple wormholes of the same type, those are treated as separate wormholes.

  • A system cannot be adjacent to itself, even if it has multiple wormholes in it.

  • A player chooses the path of adjacent systems each ship moves through during movement. If two systems on that path are adjacent because of a wormhole, that ship moves through that wormhole.

    • If the two systems are adjacent because of a wormhole and because of a shared edge or another reason, the player may choose whether or not the ship moves through the wormhole.

    • If the two systems are adjacent because of two types of wormholes, the player chooses which type of wormhole the ship moves through.

    • A player may move a ship back and forth through a wormhole between two systems any number of times, if its movement value is high enough.
