Radix.
He was the king of the mechs, the architect behind the once-glorious mech civilization. He had been the one to develop liquid metal, the hyperengine, and other advanced technologies which were still unsurpassed.
Long, long ago, Radix was summoned by Law Adepts to the Law Realm; after which, nothing had been heard from him. The mech race, without its leader, suffered a destructive blow and was wiped out from the face of the starmap by Law Adepts.
This was a humiliating history that mechs could not forget. Now, the Sentinel Goddess was saying that Radix still lived in the Law Realm. This was shocking news!
"Lord Radix is still alive?"
"Is this true?"
Dimsky and Warstar hastily asked. The Sentinel Goddess nodded. "I learned of the Law Adepts' plan to destroy mankind from the message sent by my father. He seemed to be panicking, only asking me a few simple questions about my life in human society before cutting off the line."
