Was Estar right?

Early on in Part 1 of Rome's Revolution, Rei's encounter with the Vuduri (with the exception of Rome) was invariably unpleasant. Finally, he couldn't stand it. He begged Estar to explain why they all hated him so much. Her response was very short:

     Estar said, “Your goal is to continue your journey. Perhaps to find a way back to Deucado and also find a way to tow your Ark with the Essessoni aboard, correct?”
     “You already know that,” Rei said. “Aren’t you part of the Overmind?”
     “Yes, of course,” she said. “But I need to know your intentions. You are going to thaw out your people when you get wherever you are going, correct?”
     “Well, sure,” Rei said, puzzled. “That’s the whole point of our mission in the first place.”
     “Is it your intent to unload the Erklirte weapons as well?” the woman asked.
     “Weapons?” Rei replied, confused. “What kind of weapons? We’re not carrying any weapons.”
     “Let me rephrase then,” Estar said. “When you arrive at your new home world, you intend to land the cargo portion of your craft and unpack its contents, correct?”
     “Of course,” Rei said. “We’ll need that stuff to get organized, to start our lives there.”
     “Very well,” she said. “That is all I needed to know.”

Initially, that was not much to go on. Later, Rei asked her again. This time, Estar was more blunt:

     “You are going to die,” said the voice.
     He turned and saw Estar standing at the base of the ramp. She was frowning.
     “What? Why?” he said and walked down the ramp.
     “You will not succeed,” she said. “You will die. I do not care about that. However, you will also kill Rome and many others in the process.”
     “Why do you say that?” Rei asked.
     “Because you and your Erklirte weapons cannot be released in our world. There is no place for them.”
     “I told you before, we have no weapons,” Rei said.
     “You know nothing,” said Estar. “You are just a pawn. There are forces at work here that you cannot fathom.”
     “You make it sound so sinister,” Rei said. “We’re just people from old Earth trying to find a life in your world.”
     “No, you are the Erklirte, returning from the past,” Estar spat out. “You will cause nothing but death and destruction. You will impede the progress of my species.”

Estar had tried to kill Rei several times. Couched within her cryptic response was her motivation. She really believed that the Rei and the Erklirte, the new Ark Lords would be an impediment to the development of an Onsira species, ruled by MASAL. Of course, Rei did not know it at the time. And further, as a civilian member of the Ark program, he truly thought they were only carrying implements required to build a colony. Tomorrow, his eyes are opened when he realizes that Estar was right.
