The Threemind informed you just moments after your Father's death of an experiment that took place. As soon as your father was no longer the Supreme Ruler; Cijan Anak volenteered to be “connected” with the Celestial Blood to the being that has been trapped within the Life Machine for the past century. This being, the reconstiuted remains of a half-digested alien native to Andoen, one of the three eyed giants that your race discovered the ruins of during your early Faster-Then-Light explorations of your local cluster, was your only connection to that ancient and lost race. And, given your suspicions, were likely destroyed by the worms.

”Celestial Blood being used to connect the minds of two living beings was forbidden by my father, right? Especially risky doing it to you, Cijan, one of the immortals. Doing this the moment he stepped out of command seems a little...” Treasnous. ”...Anti-Social.”
“I suppose so, but it wasn't my decision either; at least half of me didn't ask to get woken up. The Threemind organized it. This was a special case, not two citizens, but a way to access special information. And I was deemed the best fit as my... brain would be most resiliant and suitable. The Hegemony already runs plenty of experiments and programs the Supreme Ruler may not like; they're simply not privy to them all, it's an unnecessary piece of overhead. There are AI models calculating which of the Hegemonic elite might defeat you in a duel for example, your majesty, just in case to prepare for a takeover for a new Supreme and prepare the empire's models and network for a sudden shift in power. You wouldn't outlaw a precautionary measure like this too, would you?”
”Hmph. I wouldn't let myself get beat in the first place. So it's a waste of processing power.” You say, but fully accepting the thought behind it.
