If Ves wanted to, he could have tried to accommodate the Hunters.
Ves understood that if he completed his Mergewater mechs sooner, the Hunters would be able to deploy them a lot faster against the mutated voribugs.
That would have given the Rubarthans a lot more relief. The war against the bugs was extremely serious considering the Rubarthans already struggled to defend against the native aliens.
Sure, the sudden onset of the voribugs also caused the native aliens based around the Rubarthan Pact to hastily reorient their forces against the more acute threat, but that was not much of a consolation.
The native aliens had become a known quantity to the Rubarthans. The Red Cabal may be made up of extremely old and powerful phase whales, but their strategic thinking and their biases had already been analyzed to death.
That made them predictable. Manageable. Exploitable.
