Game 1: Slaanesh v Nurgle

The Psychic Scream from the Astheneia system attracted interested parties all across galactic realspace, and also from all corners of the Warp.

Each of the Chaos Powers reacts differently to the scream, and tto he growing convergences of warp energy and flow.

A Plague Legion of Nurgle on it's way to Astheneia noticed a gathering of Slaanesh Daemons and Warp Tides

The plague drones and the darkening clouds of smaller flies and monstrous insects were the only forces in the sky and thought that their masters horde with so many greater and famous Nurgle Daemons ought to be able to take that battalion of fast Slaanesh Daemonettes.

The warp flows were shaped by Cetabel the Liaison herald to the Crusade of Endless Joy, now riding a Contorted Epitome gifted her by Slaanesh, obscured that her battalion of Daemonettes included the invincible heroes of the forces of Slaanesh, Syl Eske, the Masque, an ancient Exalted Keeper of Secrets, and accompanying scouting cavalry units who had seen the Plague Drones in the sky, and maneuvered to control where the two opposing hordes actually came together

The Joyous Slaanesh Horde danced gloriously through the Nurgle Horde, speeded by the Rage-empowering flows of the Warp and their collected Slaanesh Warp energy all moving in the same direction, they seemed to be moving in fast-forward as they tore and danced through the Nurglings, Plague Bearers, and horrible giant monsters of Nurgle

First the Exalted KoS, and then Syl Eske were reduced to exactly 1 wound remaining, while dispatching Rotigus, and very narrowly winning control of the ancient grave ruins where the battle was pitched by the assuming ambush of the plague drones and Nurgle Horde

But in the end, all the units and heroes of Nurgle were discorporated and blasted back through the Warp, to where their energies eventually reformed together in the concentrating flows of the Warp, and mortally embarrassed, plotted their revenge.
