Arel and Sile's prediction was quite accurate. The empire had to face off against the elite zerg, which may have been smaller in number, but were far more terrifying in combat ability, and raw strength. The fleets they sent, hadn't had time to be refitted with the advanced weaponry they took from the rebels, and only the main battleships were built with azandium, leaving most of the fleet with subpar offensive and defensive capabilities. It is no wonder the zerg could break through their defences so easily.

Fortunately, they still had the ability to halt the zergs advance. Although the losses they suffered were catastrophic, as long as the empire doesn't fall, they can rebuild. What made them worried, was the unknown force that defended against the zerg vanguard. Based on the reports from the soldiers and conscripts. Titan-like mechas appeared from the warp point, and wiped out the entire zerg force, when the soldiers were on the verge of losing the newly formed border.

But as soon as the zerg were killed, these mecha disappeared through the warp point, and haven't been seen since. Knowing that there was such a powerful force somewhere in the empire made the ministers of the court a little antsy.

The emperor who had guessed the truth was not worried where the force was, but what they wanted to do with it. He knew the two omegas were far thinkers. They managed to kill two birds with one stone when aiding the rebels. First it would cause enough chaos, so as to halt the progress of looking for them, and secondly they could trade equipment with each other, so as to build the mechas that had just been seen.

Again, the emperor couldn't help but admire those two. With just their own twk brains, they managed to cause havoc in the empire. He didn't think they were going to stop. In fact he guessed the only intervened because they were aware that at least having the empire survive was more important than letting the zerg take over.

But they weren't saints. As long as the empire doesn't lose, they won't come to the rescue, and even if he wanted to let them intervene, he couldn't take the chance that they would completely cripple the empires foundation before stepping in.

Now the emperor was sitting in his study, wondering what their end goal was. What would the two of them hope for in the end? 

... 

While the emperor was pondering the motives of the two omegas. The women in question were currently standing on their mining planet in a daze. 

"Gone?" Sile asked. 

"Yeah" Arel replied. 

The two of them looked at each other with the same dazed faces, before finally laughing at each other. After finally calming down, Sile spoke first. 

"It isn't very surprising. There has been so many projects that needed azandium. It's only natural that it would run out eventually". 

"You're right. The defence array alone probably took a quarter of it. Let alone the mechas, the drones and what was traded to the rebels", Arel agreed. 

"Well should we look for a new source? Although we've scanned the planets around here, maybe there's another one a little further away?" Sile asked, although she didn't much believe they could find another planet. Otherwise their luck would be godly. 

"I don't think it's necessary. We have what we needed. It's just a shame that I couldn't continue to expand my mecha army" Arel said, her lips showing a slight pouting through her helmet. 

Sile couldn't help but want to laugh again. Turning around she saw the legion of colossal mechas behind the two of them. Their number had increased twofold in the time that the empire had been at war with the zerg. 

If anyone else heard what Arel just said, they'd probably want to scream at her. The power of this group of mechas is comparable to the entire military of the empire or the federation, and she doesn't feel it's enough? 

In fact Arel and Sile could live in safety and contentment with everything they have now. They truly do have an impenetrable defence. But the two of them have lived in this solar system for decades. Sometimes they get bored. Although they are still happy with their choice to come here. They sometimes want to go out to see other places, like they did all those years ago, when they were in university. 

Travelling to and from different beautiful and dangerous places. Testing wits and courage in the most unlikely of planets. Hunting wild monsters, or playing around in the black market. The two of them have been watching the same scenery for a long time, and their human curiosity is driving them to want to explore new places. 

They have built a place incomparable to anything humans have ever seen. They have made enemies with the empire, and have come out on top every single time. They have more money than they could spend in a hundred lifetimes, and they've done it all within a century. One tenth of their lives haven't even passed, and they have achieved feats others could only dream of. 

Now the two of them are finding themselves a little unsatisfied with their hermit lifestyle. They want to travel to other places, but their location has already been found. Although they can leave in disguise, and wander around, they can't leave for too long. With no one here to manage everything, they can't be at ease to just leave their life's work. 

What if someone managed to break through while they were away. Everything they've done will be stolen. Although it's highly unlikely there is anyone who has that ability, but what if? Where will they go to cry at that time? 

So although the two of them want to get on their spacecraft and fly away to visit different planets, they are not willing to do so, until they're completely sure of the safety of their property. 

Wait until the federation has taken over control over this area and they can make a deal with them to share some benefits. If they become greedy, than they'll simply destroy everything. After all, it's their hard work, what happens to it, is their choice.
