Having lost several star systems, the Zetans finally realised the threat that the Xenos posed to their existence. But they could not mount a counter-attack. The Zetan civilisation was not based around military conquest, it was based on peace and unity, and besides, there had never been many of the Zetans. The average lifespan of a Zetan was 1000 years and the maximum number of children they could have during this millennium was 5, meaning in average a Zetan had a child every 200 years. The Xenos, on the other hand, had an average lifespan of 30 years, and during that time they could have up to 40 children. This meant that the Xenos could replenish their losses quickly.
The third attempted conquest by the Xenos was the Zetan’s second most important planet, Zetani Nova. This planet was well defended and due to the Zetans being prepared and knowing they were about to be attacked, this time the Xenos were butchered with hardly any losses for the Zetans. This led to a stalemate in the conflict; every 30 years the Xenos sent a large force that ended up being nullified by the Zetan defences without reaching any progress. The Zetans, in turn, could not muster enough enthusiasm for a counterattack due to their peaceful nature, and the relative concern of the lost planets. Instead, the Zetans fortified their borders and repeatedly pursued peace, but even though the Zetans were able to nullify their Xeno counterpart’s anger and hateful intention, it still brought to no avail: The Xenos wanted the Zetans dead, and thus the two species always clashed.
The utterly pointless attacks on the Zetans were just a diversion by Rangda, to keep the Zetans unaware of the Xenos expansion, settling the uninhabited planets far away from the Zetans, and building up a massive invasion fleet.
After hundreds of years of skirmishes, the Xenos took the Zetan by complete surprise one day when they showed up in the Zetani Nova system with a 1000 times bigger fleet than they usually attacked with. Instead of the regular fleet of 300 Xeno ships, there were now 300,000 ships, and despite their vastly inferior technology, they swarmed the Zetans and annihilated the Zetan defenders as well as all Zetan civilians on Zetani Nova.
The loss of Zetani Nova finally alerted the Zetan civilisation to the existential threat that Xenos posed to them, and they managed to rally their forces from their other planets and muster a counterattack that liberated Zetani Nova a decade later. Much to their dismay, Zetani Nova was destroyed beyond recognition. What was once the most beautiful planet in the Zetan civilisation was now a toxic wasteland, and what was worse were that all the Zeto crystals, the source of all the beauty and harmony on Zetani Nova, were gone. The Zetans also found a map that revealed the terrifying truth; that the Xenos had colonised and conquered a lot of neutral planets while distracting the Zetans with small-scale battles to distract them of their true motive.
The Zetans gathered their leaders on Zetani for an emergency meeting. Their future as a living race seemed bleak and in a couple of centuries, they would be overrun by the Xeno hordes, no matter what they did to stop it. That was when Yahweh, one of the Zetan leaders, rediscovered the long-lost technology to enter and travel through the Divine Dimension, to the normal dimension and escape the Xenos threat and their apocalypse. The technology was crucial for two reasons: Firstly, going through the Divine Dimension was vastly quicker. Moving between star systems only took days instead of years. Secondly, their discovery of the Divine Dimension meant that they could manipulate other sentient beings to fight for them against the Xenos. This was the reason for Zetans to come to Earth, posing as gods and recruiting humans to fight their wars. With their newfound allies and considerably faster travel times the Zetans turned the tide in the war and repelled the Xenos time after time. The Zetans recruited the humans on Earth by infiltrating their minds and souls, and finally liberating and restoring the planets that had fallen to the Xeno scourge, back to the hands of the Zetans and their human servants.
Rangda realising that the tide in the battle had turned against her, came up with a new plan, to use her half-Zetan intelligence and abilities and altering her own genetics to infiltrate the Zetan leadership under the radar. Using the Zetan external DNA modifier, Rangda changed her appearance from the monstrous appearance of Xeno beast to that of a beautiful Zetan woman. Using a captured Zetan ship, Rangda travelled to Zetani. Since she had Zetan telepathic abilities, Rangda managed to convince the Zetans that she was one of them and soon after she managed to seduce Brahma and gain access to the Zetan leadership as well as finding out about the Divine Dimension.
Despite Rangda’s infiltration and deceit the Zetans were winning the war, and as a last spiteful effort, Rangda used her position within Zetan leadership to cause a supernova explosion that destroyed Zetani, which caused the collapse of the Zetan civilisation as well as the almost complete annihilation of the Zetan species. Having blown her cover, she was locked up by Brahma in her eternal prison in the Divine Dimension until the time when she was visited by Brahma, millennia later.
