Most magus organisations had a very strict hierarchy depending on various things like someone's talent, strength, money making ability and more. But those things were not present inside the Familia of Euphoric Temptation.
This organisation created by Elysia had a very simple structure. She was there was the founder, the matriarch and the leader. She was the highest authority.
After her, there were her personal students. Elders or such roles were not present in the middle. All the students enjoyed the authority that only a headmaster or a sect leader would have in other organisations.
Next there were the direct subordinates of Elysia. Quite a few of them were decently powerful and Elysia had given them various roles to fulfill.
Then finally, in the last position, there were the family and the subordinates of the students. From this, it looked perfectly like a regular hierarchy but with different layers.
