11 PURGE If an ability instructs a player to purge a component, that component is removed from the game and returned to the box. WORMHOLE NEXUS The wormhole nexus is a unique region of the galaxy where numerous wormholes converge. It is a two-sided system tile— the inactive side displays only a gamma wormhole, and the active side displays three wormholes. The nexus is treated as part of the game board, and it begins the game inactive, meaning it is only adjacent to tiles that have a gamma wormhole. The first time a player moves or places a unit into the wormhole nexus or gains control of its planet (Mallice), the nexus becomes active and the player flips it to its active side. The active nexus is adjacent to tiles that have an alpha, beta, or gamma wormhole. HYPERLANES When playing with five or seven players, the galaxy is set up with hyperlane tiles (see “Game Board Setup” on page 9). Each contiguous line created by one or more hyperlane tiles is a hyperlane. System tiles connected by a hyperlane are adjacent for all purposes. Hyperlane tiles improve balance in the starting positions for each player, so players do not receive extra trade goods for having a particular starting position. Hyperlane tiles are not systems. They cannot have units on them and they cannot be targets for effects or abilities.
