Fourth planet (pronounced "SOUL-talk" and sometimes spelled "Saltok") in the Soltok system.
Soltok IV is the planet that Cal Hudson contended was the actual destination of the Federation merchant ship that was attacked by the Cardassian colonists' upgraded attack craft. Gul Evek claims it carried arms, but Hudson says it had only medical supplies. It is possilbe that the planet was not only Class-M, but a colony site as well. However, it could have been merely a rendezvous point or site of an orbital facility.
