From the announcement:
Today we're really pleased to announce the release of a new adventure in Clockwork Publishing's splendid steampunk RPG, Space 1889: The Fate of Angahiaa, which is now available on Modiphius.net in print and PDF as part of our Space 1889 Collection.
Mars and its city states are the most important concerns of Earth’s colonial politics. Liftwood is a critical, highly sought after resource, and not all nations have equal access to it. But the Martians are playing their own games and seek to use their contacts with the humans for their own plans.
The Canal Prince of the small Martian city-state of Angahiaa seeks to expand its power through a trade treaty with the German Empire. But other groups within the city do not want any human influences, while others seek power over the city themselves and will use the foreigners for their own schemes.
The player characters forming the German delegation are drawn into the midst of the battles and intrigues for power in the city. They must maneuver between the decadent Canal Prince, his enemies in the nobility and guilds, as well as the priests, the slaves, and the Hill Martians of the surrounding valleys, to find friends and allies.
