Wormholes

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

Some systems contain wormholes. Systems that contain identical wormholes are adjacent.

There are two basic types of wormholes: alpha and beta.
If a player has a PDS unit upgrade technology, they can use the “Space Cannon” abilities of their PDS units through wormholes.
Players can be neighbors and perform transactions through wormholes.
There are two advanced types of wormhole: delta and gamma. These wormholes follow all other wormhole rules.
  1. The delta wormholes are present on the Creuss Gate system tile and the Ghosts of Creuss home system tile.
  2. The gamma wormholes are present on the wormhole nexus and can be discovered during exploration
