Isessos System
From Warhammer 40k - Lexicanum
The Isessos System is a system of Segmentum Pacificus.[1]
In 008.M31 during the Horus Heresy, a group of Alpha Legion warriors undertook a series of raids in the Isessos System which led to severe casualties. The survivors were transferred to the system's three Agri-Worlds, but were found to have been infected with an unknown algal strain that was harmless to humans but deadly to plant life. The strain spread, and within a year a Sector-wide famine erupted that killed 90 billion Imperial citizens.[1]
