They did, however, take up positions near large population centres, threatening to take thousands of lives with them when they go in order to pressure Confederate authorities - who had once massacred them - into helping them. Unsurprisingly, Caleb, Mezoke and Angus are chosen to go to the Neuronomes’ home planet and neutralise the unknown threat.
