Chaos Artefacts

 are structures that are left behind on the campaign map, after Warriors of Chaos or Beastmen raze a settlement.

Chaos Artefacts include:


 * Beastmen Totems
 * Herdstones
 * Chaos Portals

Chaos Artefacts will spread Chaos corruption for a time after they are created, then stop.

They can be destroyed by recolonising a settlement.
