The Chaos God Khorne sits on his throne of Bone and Blood constructed from a millennium worth of souls killed in his name, in the name of killing for killing sake. As he sits, he feels it, the call of the Warp; but this time it is different. This time it is less a call and more a plea. A plea to save it. It is a plea that promises the reward of death, blood, and, most importantly, souls.
He must act fast to answer the call. He must prevent those of the mortal plane from gaining access to any Warp energy that may be used to prevent the flow of his Chaos into their existence. He also knows if he heard the plea others within his realm have as well.
One of his advisers warns him against haste. As payment for such open and cowardly advice, Khorne sends this coward to the forges. There he will be ripped apart and put back together, but he is not reassembled as he once was. Now he is part of a machine. The coward is reborn a Soulgrinder. There in that cursed form he will stay until Khorne is satisfied that he has shed his cowardice. Khorne knows this is unlikely to happen.
Khorne calls on one of his most trusted generals. Skulltaker is always eager to cleave heads in the name of his Master. Skulltaker shall be sent to this planet where the Warp cries out. There Skulltaker will destroy the devices the mortals have constructed to harness and focus the power of the Warp. Khorne has seen such devices before. These teleporters cage the energies of the Warp. How dare these mortals try to control what is not theirs.
Skulltaker and his small yet powerful army will assess what will be the battleground as well as determine who best to align with to achieve their goal. Many powerful factions will converge on this planet. It is always the way with places of power. If there is an opportunity to fight alongside others in order to more quickly achieve the goal then so be it. Skulltaker bristles at the very suggestion, but settles when Khorne reminds him of two things. First, Khorne is Master and Skulltaker is not. Second, Skulltaker can kill his allies once the Warp is freed.
Khorne dismisses Skulltaker once his orders are given. Shadows within the Chaos God’s throne room stir and from within emerges the form of the Soulgrinder. Its metal legs grind with each scuttling step. Khorne watches it and considers what might be found on the planet. Something about the place feels oddly familiar, like an old wound never healed.
Within the Realm of Chaos all distances are both great and small depending on Khorne’s focus. Time can compress and expand but is outside of his influence. This distress call from the Warp could be from the past or present. Warp portals, though loathsome, are not uncommon constructs. The plea Khorne is answering might be the result of some greater disturbance. Either way, the call must be answered. A God of Chaos does not rethink his strategy once the plan is set.
