Primus Ruining

The Primus Ruining was a war between the Imperium of Man and the Bonapa Waaagh.

The war began in 387.M41 when a colossal Ork warband under Bonapa da Great attacked the Mercatorius System in search of loot. At the time, the system was one of the wealthiest in the local cluster, with Mercatorius Prime being a centre of tremendous riches.

While the Imperium managed to eventually win the war, to defeat the Waaagh eventually required that the planet of Mercatorius Prime be razed, to both kill the overwhelming number of Orks and prevent their spores from creating problems in the future.

The razing of Mercatorius Prime had a tremendous effect on the world. Those who survived the razing were left with a largely arid planet and with their capital Hive City, Varachia, left a ruin. This resulted in the power over the system shifting to Novus Mercatorius and the planet of Mercatorius Prime becoming a hotbed of criminality and gangs. These factors laid the foundations of the eventual Gracchian Uprising.
