Population Migration / Travel
Humanity uses technology from the Imperium to start their colony mission to expand.
Humanity built 500 colony ships to populated nearest stars. The problem being the ships can only housed 200 people. Making population growth slow. So humanity made breeding pods named ‘Ark pods’ that will have 20 eggs and sperm. They would have the ability to create a full grown human. The Pods can easily be stored in ships. Making the ships only carry over 200 pods. The humans born in the pods will have a extreme sex drive, that will make them have a family of 20.
