Realm

A realm is a world that is made up of several species, cultures and natural features. There are at least thirteen hospitable realms, each one under the protection and keeping of a realm guardian. There existed at least two more realms before they got destroyed. Such realms can be illegally accessed through passageways, typically infiltrated by 'realm pirates'.

Structure
A standard realm is planetary in form and most, if not all of them, are large in comparison to Earth. Some realms may be closer to each other, some smaller and bigger and others and some curve around each other.

Each realm and it's continents have an opening to the void, including oceans if they exist. Realms are legally connected through 'void bridges', which act as commonly travelled grounds and trade routes. If one could endure the harsh yet maddeningly empty conditions of the void, they may be able to illegally traverse into other realms through smaller, remote and non-bridged entrances and pathways. If one attempted to leave a realm through any area that isn't punctured and open to the void, they will be pushed back and forced away from its gravitating barrier.
