Stella System

The Stella System was a virtual reality construct in the city of Ateliesta. It was governed by the artificial intelligence Stella.
The Stella System was built by the last remains of humanity in a future world. It was designed to make an artificial world just for the user, based on their wishes. The central A.I. found out their emotions and thoughts, and built a world based on them. In the virtual reality, the user forgot their former life. Based on information from Tensei Shoujo to Tensei Shounen (Reincarnated Girl and Reincarnated Boy, 転生少女と転生少年), the only way to truly escape from your own artificial world may be to die in the world.
The system was destroyed, when Dr. Realist released the Stella from the system with Rho. Stella went on to become Lambda afterwards.
Theories
-If Ateliesta is a world made by Kuroneko Antique, it is not a real world either. Fans theorize, that Ateliesta is also just a simulation like Stella, with the central A.I. being Atelier. This would make the Stella System a simulation inside a simulation, and it would mean that nothing happening in the Fantastic Garden or Star Girl and the Illusion Paradise would have happened in the real world.
