Generation ships were an ancient class of vessel used to colonize worlds prior to the advent of hyperspace travel. They were massive ships utilizing different compartments for growing food, primary and secondary power generators, living quarters, and entertainment modules. The main purpose of its design was for the primary and future generations to teach their progeny how to run the ship and colonize worlds. The knowledge was passed down until the destination was reached and the colony was established.
