This was not just imaginative thinking. They had all witnessed it. Those who succeeded in laying an ambush that killed a voider are now extinct races. An enemy you can't kill in a war for fear of extinction. Why continue such a stupid war?
They very much understand such logic. The organization kicked them off the server because they understood they could fight the whole universe without breaking a sweat. They should have known from the onset that they had walked into a trap. Damn! Who would be stupid enough to pit the downfall of their race? Haa! It's reversed now. Previously, they were strong, and humans were weak. They bully the humans into forfeiting what belongs to them.
But now, humans have grown strong enough to challenge as many races that pissed them off. They saw this coming but could not do anything to stop it. They can only blame the Garden of Eden for being stingy and playing favouritism.
