Recidious System
From Warhammer 40k - Lexicanum
The Recidious System is one of the Galaxy's Systems, that is controlled by the Imperium.[1a]
History
In M42, it was invaded by Hive Fleet Leviathan and among the Imperial forces that came to its defense, were the Ultramarines Chapter's 2nd Company, the Astra Militarum's Cadian 8th Regiment, the Adeptus Mechanicus, the Inquisition, the Deathwatch[1a] and the Imperial Navy.[1b] However, the Recidious System was later invaded by the Thousand Sons Traitor Legion as well, which has led to the Imperium now fighting both invading forces at once.[1a]
