The Irrea Mist is a a pale blue nebulae located in the centre of the Rim Worlds region. It stretches from the Orelon Belt in the east to the Keltros Expanse in the west. From the Hapan system in the north to the Cloak of Alsace in the south. Most parts of the mist were explored during the First and Second Expansion eras, but were not completely mapped until the start of the Third Expansion Era.
The concentrated radiation and thick nebulae clouds in the region, which connects to the Transitory Mists, makes navigation and travel in the area extremely difficult. Many ships have been lost in the mists over the course of the centuries.
