“Rebuild your world, rebuild your race, rebuild your empire. Rebuild it all. But make sure you rebuild your ideals too. Rebuild the principles that made you a great and honorable galactic power in the first place. Don't prey on the weak. Don't steal from the helpless. Don't murder the innocent. Be a force for good, not a force for yourself.” PrinciplesPowerHonorFutureIdealsGoodGreatHonorableDoctor WhoEmpireRebuildForce Of Good Book:Doctor Who: The Silent Stars Go By Source: Doctor Who: The Silent Stars Go By
