Legion-7's refusal not only destroyed his plans to acquire information about their special reward, it also made it impossible for him to complete his deal with the great mothers.
She wanted Legion's weakness before the attack of the Phoenix race on the Stellaris plane and she was willing to pay heavily for it but he didn't have it. He couldn't even tell her if he had it. That will be breaking the rules of his position.
The best he could do was get her in contact with the first sage. The first sage told her something which made the great mother happy. She was happy enough to invest 3 great mothers in the attack on the Stellaris plane.
The first sage was also happy to acquire some much-needed information about Legion-7 from the great mothers. Only he was not happy.
The good news is that he is not alone in that unhappiness. The invasion of the Stellaris plane by the dragons, phoenixes, and Stellos ended in failure so the great mothers became unhappy.
