The structure of ÄON is comparable to that of a black hole. Energy is located in the middle (the main choice). Energy keeps the whole system from collapsing and assures that the borders of what is happening are never exceeded, which would mean that the user Is irrevocably lost forever. Photons (event worlds) are located around the center which are, in their own right, so complex that they form their own individual universes. The user is constantly confronted with fragments from the individual worlds and it becomes necessary, sooner or later, to react to them.
