An Echo of their own. Primordial Demon Beasts can't be killed... unless the very thing that gave origin to them was used. They all felt it when that pressure assaulted them a few minutes ago.
"Still..." Roan had his doubts. "The Werdlem Empire knew you were coming. How?"
Default shook his head in response. "I don't know. I told you before. The Echo is not a sentient being. The Echo doesn't give me orders through words. It simply lets me know what it needs through our connection. I was the very first Primordial Demon Beast, so our connection is strong enough for it to happen. And through me, I can pass the same orders forward to the others."
Roan pondered a bit. "Alright. Then what happened after you were all captured? Obviously, the Werdlem Empire hasn't created a new Echo. Had they done so, they wouldn't need the Bubble anymore. The entire Great Void would be in their hands."
