Wormhole Nexus

Marked text is printed in red in LRR v2.0 (new or changed with Prophecy of Kings)

The wormhole nexus is a system tile where several wormholes converge.

The wormhole nexus begins the game in play with its inactive side up.
  1. The inactive side of the wormhole nexus contains a gamma wormhole. The active side of the wormhole nexus contains an alpha, beta, and gamma wormhole.
  2. The wormhole nexus is treated as part of the game board.
  3. The wormhole nexus is on the edge of the game board.
After a player moves or places a unit into the wormhole nexus, or gains control of the planet Mallice, that player flips the wormhole nexus to its active side.
  1. When a ship moves into the wormhole nexus, the nexus becomes active at the end of the “Movement” step.
