Teraell

Year 917 · The Age of Oath and Brass

Teraell is a world of six city-states bound to one another by trade, by the Pact of Reason, and by the Oathbond — the standing every free person is born into and must keep, each day, through their own conduct. It is a world of skaerflint rifles and clockwork, of rifled naval cannon and difference engines, of ships that carry the whole of the Known World's commerce along a single coast. It is also a world where slavery is legal in every city, and where the argument over whether it should be is the one argument nobody has finished.

This wiki is the reference companion to the Oathbond World Bible. It is written from outside the world: it says plainly what is true, including things nobody living in Teraell knows. Pages that reveal such things carry a {{Hidden truth}} box. Read Meta:Conventions before you write or build anything from it.

This wiki is fiction for adults. It depicts slavery and other mature subjects as facts of an invented world, not as endorsement or instruction. By reading it you accept the Meta:Content Notice.
