I have an idea of a universe where the planets are all... coins, or discs, or pizzas. One of the planet is named Twiside.
Twiside is a flat disk-shaped planet resembling a concave coin. Due to the nature of universe itself, the inhabitant of Twiside can technically see the otherside around a million kilometres above them. In reality, only the inhabitant of the darkside can see the lightside. The sky of the lightside is too bright for the inhabitant to see the darkside. This bizzare phenomenon hapens because the universe in which Twiside reside (TUIWTR for short) is a four dimensional torus. To wit, TUIWTR wraps around itself. If you go far enough, you will return at your current position.
TUIWTR is, for a lack of better term, extremely flat. In order to reach back to the point of origin, you have to travel for millions of lightyears in the direction parallel to the plane of the disks. In a direction perpendicular to the plane of the disks, however, you only need to travel four lightseconds.
From darkside, the lightside appears as a stationary "moon" right above everyone's head.
Just like our universe, TUIWTR is filled with celestial bodies that orbit each other. In Tuiwtr, however, their equivalent of sun is a moon-sized disk (called light plate) that orbits the earth-sized planet. (Twiside diameter is actually twice of our earth). The flat and wrap-around nature of TUIWTR made it so that the inhabitant of Twiside can see several copies of the same light plate that orbit their world. The closest one to them always hover at fourty five degree from edge of the worldplate.
Each lightplates have two sides that emit different kind of energy. One side emits visible light and little else, the other side emits the ergon and almost no visible light. This causes Twiside to have a side of perpetual warm night and cold day, called darkside and lightside respectively.

Can anyone understand the shape of the universe described by those words? I think I should make a diagram.
