In this small safe, information pertaining to Curvature Technology was contained, which in the past had not been disclosed to several Human Bases behind us, nor stored within the large safes of the trading markets.
The matter was too important; even Humans of the same origin could not be completely trusted.
Should this information be exposed, a multitude of interstellar civilizations would come flocking, and the plans of the New Human Civilization and the Tos Civilization might very well collapse. But now, as everyone had already decided on the entire plan, there was no problem entrusting it to the rear bases.
If not successful, then one must be prepared to sacrifice everything!
Cocos-shaped Wart said, "A triviality, in consideration of our friendship, we won't charge extra. Please sign an additional contract right here..."
So, all the work was completed, and both parties formally bid farewell.
