My memory is a mostly a library, as I have only just begun. It has four different levels reached by a hovering platform. The basement is where I keep basic information.
The main level is for more in depth information. Such more complicated of the basic three level holds titles and observations I would gather. The last level would be the roof. Here there is a foutain and a garden and it would hold world languages and other ‘world’ information … or at least I hope so, as I have only just started.
