Ryla village, Vlera realm.
After finding out that the heavenly energy used here is similar to his realm's, but its heavenly aura is too powerful and is pure. The heavenly energy technique that is used by the solarians was taught by their king Leon when he freed them.
The demonoids are the minorities who worked as the slaves for the majority Thayilrens during the Thayil dynasty era under the previous king's rule, they were stripped out of their basic right and were treated worse than a slave, the untouchability and discrimination was at the peak during that time of era, but this was all changed in one day when Lord Leon stormed into their realm and exterminated the powerful elite guards of Thayil realm and executed their previous king.
After that the heaven crowned him as the new king of Thayil realm, but he changed it to Solaris when he came to know that the demonoids were treated as slaves by the Thayilrens and also changed his surname to solarian. He then gave all of the demonoids his surname to use by this way the Thayilrens had no other choice but to accept them as their equals and had to treat them with mutual respect. Lord Leon gave freedom and equal rights to the demonoids and also taught them some heavenly technique and magic as during the early stage of his rule the demonoids were still not allowed into the academies but later when Lord Leon agreed to marry the previous crown princess Kristen Thornfield due to political pressure and also for the wellbeing and harmony between the citizens, gradually the demoniods were allowed into the academies and also got many other privileges which was only enjoyed by the Thayilrens before.
This concludes in only one answer, the user of this power can be only his king who was gone missing during the battle with rebels 8 years ago. He then clears his mind and stops over thinking to concentrate on the source of the power to trace it.
He then finds the location from the traces left behind from the heavenly energy of his king; he then transforms into owl and flies towards that direction. After a passing few kilometers, he finds the location from where the source of the power was emanating and also sees a small mansion.
He then returns to his original form and begins walking towards the mansion, but he was also cautious as if he deduced wrongly and the person is not his king then it would spell trouble for him as he is not powerful enough to fight this person.
"Who goes by there? stop lurking in the shadows and show yourself" Rowan roars intimidatingly, after Rowan's warning Deshru reveals himself before getting turned into ashes by Rowan.
"I am Deshru Kral Solarian, I am here to investigate about the incident happened in the village" he blurts out even before opening his eyes after coming out of the shadows, but when he opened his eyes and saw the man before him. His eyes formed tears when he identified that majestic moustache and the scorching sun eyes in Rowan.
He then immediately kneels down out of respect and places his right hand over his left chest and says while tears are running down from his eyes "Long live the King". Lena is confused and is also shocked as she stood beside Rowan, Rowan then smiles awkwardly as a response to Lena.
