Tetryon Field

Common card from Premiere (1994)

Intense masses of subspace particles, unstable in normal space, which require ships to route through safe corridors.

Plays crosswise on any spaceline location. All ships must stop here before proceeding on next turn, unless Navigation aboard.

Rule notes

Official Runlings:

A ship without Navigation aboard must stop moving at the location of this event and cannot move for the remainder of the turn, but is not "stopped" (e.g., it may initiate battle or attempt a mission).
