Thadius didn't blame his mother for this since he knew she was just worried about his future and that with his personality he would end up alone. Another reason to return was that when one turned fifteen they were eligible to enter the academy.
Not all talents were born in powerfull clans and since talent needed resources to move forward so the academy was the place that they dreamed of. The Lunar Star Academy didn't fight for hegemony of the planet they had one purpose and that was training talents. They gave the students opportunities to earn resources and move towards a better future. It wasn't just the poor clans that went to the academy even the four great clans sent their top talents so that they could learn and make connections.
At the Lunar Star academy they got exposure to other talents made friends, enemies and learnt to be self sufficient rather than relying on the clan but the main reason is that the Lunar Star academy is just the branch academy of the True Lunar academy which has it's headquarters set up in the Yoreh Major World. The top student have the opportunity to clash with students from other Minor Worlds and evey generation a select few are chosen to go to the major world to study at the True Lunar academy.
It is damn near impossible for those below the eighth stage to transverse the void and go the Major World so this opportunity was so rare that it made even eighth stage cultivators salivate.
Thadius was also very interested in this so he was also going to the academy. There are two ways one can enter the academy the first is by passing the entrance test and other by recommendation.Thadius decided he would enter without the exam since with the clan's resources and his father's backing it would be easy. Though many top talents would purposefully take the entrance test to show the world they aren't depending on the clan Thadius wasn't like them. He believed life is not fair and since he was born with better standing than others he might as well use it for his benefit otherwise what's the point of being in a powerful clan.
The academy divided the students into outer, inner, elite and core disciples. The elite disciples had the chance to fight students from branch academy of other Minor Worlds. As for the chance to enter the True Academy, only core disciples had a shot. When passed the entrance test most would be other disciples and only the best of them would be inner disciples. With the recommendation that Thadius got he was directly made an inner disciple. For one to become an elite disciple and above they had to chosen by a teacher which was very difficult since all the teachers were the inner disciples of the True Lunar academy and they were here on academy mission to train talents. If someone they trained manages to earn a spot at the True Academy they would also recieved merit.
Lunar Star Academy wasn't located in the human region instead it was a ginormous flying island in the aquatic region with numerous actual Islands surrounding it.
