Oriontis: The Lost Kingdom is a city-builder where every choice shapes the destiny of the kingdom. Build and design over a hundred unique structures, drive a vibrant trade network that spans the skies, defend your routes from pirates, and withstand natural disasters such as meteor showers.
Oriontis
Steam“Set sail and explore the farthest reaches, expand the frontiers and bring the kingdom back its wealth.”

Logistics buildings line the horizon alongside imposing port docks. Goods cross the skies, are stored, exchanged, and distributed in your city's ports. Trade with other cities, outposts, and even ephemeral smuggling enclaves, where you can find goods that are almost impossible to find in the kingdom's established trade.

Over one hundred buildings spread across eleven ministries shape a city that is constantly evolving and demanding new goods and services. Entertainment, military power, government, religion, healthcare, roads, housing, agriculture, logistics and trade, industry and raw materials, as well as decoration: each sector is key to sustaining and expanding your kingdom.

The constant threat to the kingdom: notorious pirates roam the skies in search of ships laden with goods to plunder. Keep them at bay and protect your trade routes. Building a city in the harsh environment of space is no easy task; you will have to contend with natural disasters such as meteor showers.

The King and the court of Oriontis demand that you perpetuate their legacy through majestic works entrusted to you. Carry them out by setting up production lines, organising specialised labour, and sustaining a complex process until such a construction is completed. The economy of your city and the spirit of its people will be put to the test.

Many buildings can be visited and enjoyed by the people of your city, such as religious altars, gardens, or market squares where shows are held. You can watch your town come to life and enjoy a well-planned urban design.

Build immense and powerful battleships, gather wood and forge bronze for your ships. Set up production lines to supply your shipyards. Buy and sell ships throughout the kingdom and increase their capabilities with special upgrades.

The cosmos remains uncharted territory. It will be up to you to draw new maps as you discover unknown ports, untravelled trade routes and hidden treasures. On your voyages, you will also be able to rescue shipwrecked crews and find forgotten enclaves, exotic goods and mysteries that will test your mettle.

Your decisions alter the course of history: who you choose as an ally, whether the spiritual cult of Serenity or the holy order of Sanctum; whether you decide to abide by the law of the kingdom or risk negotiating secretly with pirates. Each choice affects how events unfold and will shape your destiny.
