The Office of Colonial Development was an independent agency of the Compact. It was tasked with overseeing allocation of newly claimed planets to core worlds and constituent authorites and assist with the development of colonies on behalf of their parent worlds. Additionally, the OCD, as it was sometimes called, would assume authority over a failed world, making it a protectorate.
In the Interstellar Era, OCD became more feared than taxing authorities and overzealous militaries for their iron grip on colonial settlement.
