Everyone thought that he died. Only Sarcony knew the truth. He simply discarded his physical body and tried to escape in the Astral body. Sarcony's threads had been extremely modified by the awakening into spirit of the sun. They were now made of solar aura that was no different from pure chakra in terms of detection but varies by a large amount in terms of functions it does.
It could bind astral bodies and even destroy/purify them returning the soul to its untainted, pure state, allowing it to re-enter the reincarnation cycle. They can literally wipe the very existence of the individual off the face of the multiverse as it is the astral body made of mind, intelligence and ego that carries the identity, memories and the sense of self of any living being of the multiverse.
They have changed into something different at a fundamental level. For her Unveiling gift read;
3. Twine of Norns [intermediate level]
They have changed from ordinary threads made from untainted Chakra to the twine that controlled the very fate of those bound by it. They now had the ability to bind and affect Astral bodies which is generally impossible to physical/mortal objects and energy of any mortal kind.
The threads that caused the inflation followed by explosion of his body were also responsible for binding his astral body. With a facial expression (not that it is visible to anyone locked within the fetters of the 'physical body' ) that said 'IMPOSSIBLE', he remained immobile, even forgetting to struggle and free himself from the threads that were imprisoning him in place.
Sarcony never expected her silly experiment to succeed and prepared a second plan as a fail-safe but was nevertheless happy that her first plan succeeded. She immediately pulled him back to throne room and shoved him into the hands of Vermillion bird after thoroughly securing him. Turning around, she saw her sister pummeling the assailant who wounded the king.

The king, healed to some extent, tried to talk to Aria only to be bound by golden, hair-thin threads emnating from her fingertips. " You think cheating me is that easy!!!! " " Aria, what is happening? " " Sis, he is one among the people trying to attack the kingdom. There is something happening right in plain sight we aren't able to figure out. Speak, What is the plan?? "
Aria's words surprised everyone present. There were dissendents but none dare raise their voice against Aria who was extremely serious, releasing abnormal amount of suppression. Even Celestina, who thought of declaring there was some kind of misunderstanding, was shut down by it.
" HAHAHA.........., I COULDN'T FOOL YOU IN THE END AFTERALL. NICE WORK RECOGNISING ME. YOUR KING IS SAFE, CAPTIVE OF MY LORD WAITING FOR YOU AT HIS PALACE. YOU, WHO KNOWS WHAT A REALM KING IS MUST DEFINITELY KNOW WHAT A REALM KING'S ABODE IS. I REPLACED YOUR KING EONS AGO. WHEN WAS IT? AAH...., IT WAS DURING THE DEMONIC BEAST STAMPEDE. HE FOUGHT VALIANTLY BUT VALIANCE CAN ONLY TAKE YOU SO FAR. HE WAS TAKEN INTO CUSTODE BY MY LORD WHO ORDERED ME TO REPLACE HIM AFTER TRANSFERRING HIS MEMORIES TO ME. EVEN THE SERAPH MAGE CELESTINA COULDN'T SENSE ME. ITS NATURAL. MY LORD IS A HAND OF DEVIL LEVEL DARK MAGE. SHE STOOD NO CHANCE AT ALL ANYWAY. "
" Don't you fear your lord will kill you if you reveal all his secrets like that? " " YOU MUST BE JESTING. MY VERY MISSION WAS TO TRACK AND SEND THE LAST LIGHT MAGE TO HIM. THAT WAS WHY I REIGNED LIKE A JUST KING, BRINGING PROSPERITY TO PEOPLE OF THIS KINGDOM. I MAINTAINED FRIENDLY RELATIONSHIPS WITH NEIGHBOURING COUNTRIES PREVENTING UNNECESSARY WARFARE. I PERFORMED ALL THE DUTIES A STUDENT MUST DO SO TOWARDS HIS TEACHER TOWARDS MY TEACHER CELESTINA. I NEVER MISTREATED MY FRIEND GUSTOV. ALL FOR THE SAKE OF FINDING AND LEADING YOU TO MY LORD. I DID IT. BEFORE KILLING ME, PLEASE FULFILL MY LAST REQUEST, PLEASE MEET MY LORD. HE IS WAITING FOR YOUR ARRIVAL. "
" If you really care for this kingdom, why did you send hordes of beasts to destroy it? Don't lie to me. I clearly sensed your aura in every beast I purified. " " NOTHING ESCAPES YOU. I AM IMPRESSED. I NEVER CARED FOR THIS KINGDOM. I DID WHAT MY LORD ORDERED ME TO. THAT'S ALL. "
" Quite heartless, aren't you? " Aria freed his restraints without harming him. " Aria!? " " Sis, everything he spoke is the truth. He never misused or abused his authority. You know that as well. " " But!? " " Speak, don't you serve him because he is the strongest? " " WHAT ARE YOU SAYING? I SERVE HIM BECAUSE THE VERY REASON FOR MY EXISTENCE IS HIM. I AM A MERE PUPPET IN HIS HANDS, A CUTE, LITTLE, SELF AWARE PUPPET. WAS THIS ANSWER EXPECTED? "
