From the introduction:
Sharded RPG is a fantasy role playing game set in the Sharded multiverse. The Sharded multiverse is divided into a multitude of different Shards, as varied as can possibly be imagined.
Each shard is its own self-contained universe, however, there are many different ways to jump between shards. Some people are able to do it at will, others are carried away in a dimensional rift and still others use science or magic to create portals between the shards.
In such a world, adventure is easy to find and many people spend their lives caught up in it.
