The survivors of the war that almost destroyed the seamount savored the euphoria of victory for a few minutes before they finally calmed down. They didn't have the strength for a long fancy celebration, and besides, that was not their style.
Not only that, after the battle, they were exhausted both physically and mentally. To remedy that, they needed to feast and eat to their satisfaction before getting the much-needed rest to recover.
From the original 40+ Draconic Lizards that debuted in the battle, only 11 were left but these guys were far more different than how they were before.
It was like they were caterpillars before starting the battle, but now they had all the juices that they needed to evolve to become full butterflies.
The Skill and Adaptation points that they got from this battle alone would ensure that they grew far more powerful after spending it instinctively.
