In the penultimate mission of the Star Trek: Judgment Rites game, the Enterprise must stop a ship populated by mentally-challenged humanoids from landing on a Federation colony. This interacts with the overall story arc of the game in that,
It is revealed that the crew is being tested by the Brassica in how they deal with the situation on board the Compassion.
However, the humanoids on board the ship are clearly not Brassicans themselves, as the Brassicans resemble "giant beanstalks" (according to Scotty). So my question is Was "the Compassion" simply detected and then used by the Brassica or did they construct the entire ship and populate it themselves?
In other words, what is the relationship between the Brassica, The Builders, The Phays, and the residents of the Compassion?
