Golarion Diplomacy

A Diplomacy variant on Golarion's Inner Sea

diplomacy

It is Spring 4701 AR, and tensions are rising around the Inner Sea.

Map of the Inner Sea region of Golarion in Spring 4701 AR, showing the seven powers' territories, supply centers, and split coasts
Submitted to the 2026 DiploStrats Variant Contest.

Powers

Golarion Diplomacy contains 36 supply centers. Control 19 to solo.

Rules

As in classic Diplomacy, powers can build during winter in their own home supply centers, provided that the supply center is unoccupied and remains under their control. In addition: Absalom, the City at the Center of the World, is a neutral build center. Any player can build a fleet (or army) in Absalom, so long as it is unoccupied and under their control. Absalom's special build center is marked with a star, as are the home supply centers — other supply centers are marked with a circle.

The Eye of Abendego is a vicious, permanent hurricane. Units cannot enter the Eye of Abendego — it is impassable.

All other rules are as in classic Diplomacy.

Split Coasts

The provinces Corentyn and Ravounel have split coasts.

Fleets can move between Vyre and either coast of Ravounel, the Steaming Sea, or Conqueror's Bay. Armies can move between Vyre and Ravounel.

The Hespereth Strait

Khari contains the Hespereth Strait, and behaves as Constantinople and Kiel do on the classic map. Fleets can move between Khari and the Mid-Arcadian Ocean or Western Inner Sea (as well as Azir, Manaket, and either coast of Corentyn). Armies can pass through Khari to travel between the northern continent Avistan and the southern continent Garund.

Provinces

Armies can only get to and from Absalom, Mediogalti Island, Okeno, and Jalmeray via convoy.

The unlabelled lakes and islands are drawn for flavor and do not affect adjacencies.

Adjacency Notes

I tried to make the map legible, but to clarify anything that might be ambiguous:

I can clarify any additional adjacencies if needed — or just provide a file with the full adjacency graph, although I might need some time to thoroughly proofread it first. I also think I have an svg that should work with Discord bots, though I still need to actually test it.
