Greyhawk: Rel Astra

Rel Astra is one of the major port cities of the Great Kingdom. It is an old city of the Aerdy, the original seat of the early Aerdian Church of Law and once a capital of an Aerdi kingdom until the crowning of the Overking. Once the Great Kingdom was declared in Rauxes, control of Rel Astra was given over to a ministerialis who served as constable and mayor in the Overking's name. The post continues, but it now belongs to a hereditary noble line whose interests have diverged from those of the Malachite Throne.

Like the lords of the Iron League region, the Constable's financial interests lie with the burghers and trade, and he resents the grasping and peremptory ways of the Overking. He is also wary of the covetousness of Medegia's Holy Censor.

While the more fierce-tongued members of the city's council urge swift action, the Constable chooses to slowly build his forces and bide his time.

The original Folio had an apparent editing mistake that listed Rel Astra as the capital of Medegia, so a thought it was worth making a nod to that in the history. Though the Folio never mentions it, the title of Overking suggests their were (at least once) subordinate kings. I figure there must have been multiple, petty Aerdian kingdoms that were united.
