Hell at Tarlius

On Tarlius the Imperial position was given a great boost with the arrival of significantly more Mechanicum forces, bolstering the Imperial Guard and immediately taking on the heaviest front line fighting. In early 12.017M42 the Emerald Serpent had scored a victory, but had failed to remove the Imperial forces from the planet. Now, with the Imperial Guard stuck in defensive pockets around key objectives, the daemonic legions of Tzeentch were called upon once again to dislodge the Imperium.

The first daemonic incursion occured on 0712.017M42, but the fresh Mechanicum forces were able to prevent a breakthrough, rescuing and joining up the Imperial defences on the planet for the first time. Following this, several more incursions were recorded by the Emerald Serpent, with varying results. On one occasion the Emerald serpent were completely decimated, but on another, the Mechanicum force sent to intercept was all but wiped out. By 1412.017M42 Tarlius 3 had become a living hell. Imperial Guard units and loyalist mechanicum forces held on to bases and positions on the dusty plains, but were constantly exposed to daemonic incursions and guerilla attacks from chaos forces, led and organised by the Emerald Serpent. There were no clear front lines, with chaos forces simply melting back into the warp or their mortal troops disappearing into the vast badlands. The Imperium realised that wrestling the planet from the grip of chaos may end up a very difficult proposition.
