The Crallicans were a humanoid race native to Crallica. When their planet began dying, they tried in vain to design a spaceship to save themselves. One day a Vogan ship arrived and offered to transport them to their own world. The Crallican leaders accepted the offer, overruling the few who were suspicious of the Vogans. Once on board, the Crallicans were processed and placed in suspended animation for the voyage. When the Third Doctor arrived on the ship, he awakened Trandi, learned of the situation, and rescued her people from Vogan slavery. Once the Vogans were defeated, the Crallicans settled on their world. (COMIC: The Vogan Slaves)
