The Tannery States are ruled by the Tannery Council from The Tannery. The Tannery is at the heart of the alliance that binds the states together. The original agreements were signed on a small island, used as a tannery, situated at the confluence of two rivers and precisely at the point that the three largest states met. The Rulers of Serise, Krote and Momir came together and agreed the first of the agreements that would eventually lead to economic and mutual security agreements between the three states, that grew into a full-blown union when the other local states joined with each ruler building their capital around the tannery island. This created the metropolis known simply as The Tannery.

The cities that grew up around the Tannery are, together, the primary settlement on the whole Telida Peninsula, and the largest settlement in The Hann Empire. The Dukes rule their own ‘quarter’ while the Lord Tannery (The high priest of Abadar) rules the smallest central island ward and acts as arbiter. The three National Wards are, each, fairly normal small cities, although Datsyn’s College, in Serise Ward, is a Universalist Wizard’s College, offering training in the Arcane Arts. Many of the Lords Serise are alumni of its hallowed halls, and it is favoured by that house. Central ward houses three great cathedrals and the Tannery Council Chambers. Abadar’s faithful oversee administration across the metropolis (Part of the original agreement between the three states), and the Arch-Banker Chairs the Tannery Council. The Temple of Pharasma oversees the noble catacombs, and the temple of Iomedae trains the city guard.

Over the years, the composition of the council has changed to include representation from the smaller states. The Dukes each have four representatives on the council, while each of the other states (including Tusk) have a single representative each. The council is configured to see that the various states get along peacefully, rather than be responsible for over all policy and direction. However, they do levy a small national tax, on behalf of the Central Ward, to fund the cathedrals and a small Tannery Guard.

There is a general frustration that The Farran Isles, which are not part of the Tannery League, has a bug influence on Tannery Trade. It has been discussed many times, but there is little that anyone can do about it. That would, probably, take a war of conquest, and that would (most likely) see the end of The Hann Empire.

• Serise - Led by Imperial Duke Rodney III, Serise controls a large section of the main city, that includes the city's Magic University. Many members of house Serise study at the university, and the current lord is an accomplished mage. Beyond the city, the duchy is based on market towns and a rural village economy. There is always some concern about House Serise, as their magic university had a short period when it specialized in demon and devil summoning. The arrival of Iomedae's Mission, put a stop to that - but fear lingers in the memory.
• Krote Led by Imperial Duke Stanley, the House of Krote rule their holdings from a small palace in their city, but are generally seen as more 'rough and ready' than their counterparts, with some of their number training as Rangers. Away from the city, Krote is primarily an agricultural state with good land for both crops farming and animal husbandry. However, the families original holdings were in one of the state's wetlands, and family legend has it that, in the early days, the family holdings were saved from attack when the invaders disturbed the toads, and the great croaking woke the families defenders. The family motto is ‘Die Kroten Sind Unsere Starke’ (‘The Toads Are Our Strength’). The Duke of Krote holds the secondary title of Baron Berhof. Berhof is a small mountain state that is not a part of the Tannery League. The female heir of Berhof married into House Krote, and it has been part of the family collection ever since.
• Momir Led by Imperial Duchess Daphne, Momir is the smallest duchy and, perhaps, the least interesting. It doesn't have any special history, just a hard-working Royal family who manage their holings well.

• Tusk is unusual, an independent city-state founded by Henry deLemaistre under a Charter to tame the lawless lands north of the central swamps. Now most of the northlands look to them for guidance.

The lesser estates of The Tannery League are scattered around the edges of the royal estates that belong to the dukes. The lords of Far March and Rilltops currently represent their peers in the Tannery Council. These lesser estates are all based around a town (often a large town) with satellite villages and the occasional market town. Most make their money by sheep farming in the local hills, then spinning and weaving in the town. The best quality Tannery Hinterland wool is very well regarded, both nationally and internationally.

Achehold, Pretipark and Far March, are primarily human settlements, but have more half-elves than may other rural areas. Some have been adopted at birth from Elven Mothers, who wanted to find a home for an unwanted child.
