Big Obduratius just woke up.
A nearby tech-priest pulled a lever, and the back of the Leviathan (one of many that made up the amalgam of titans, troop transports, and other things that made up the mobile fortress) opened up to allow the towering Dreadnought to walk out. For whatever reason, this one in particular didn’t have treads, just large feet. I learned later that they had a tendency to slide backwards when its Thunder Fists were activated, not so good when there was an army behind it, or if you’re trying to hold back a particularly large orc.
I wanted to see this thing in action, and an excuse to get away from the drab corridors of the “The Pertinacious”, so I used my Inquisitorial authority to commandeer a nearby Land Speeder, ignoring Dastun’s warnings about following it to the front lines. Despite the fact that it was merely walking, the sheer length of its strides made it difficult to keep up with. Luckily, the march of the Partinax and the speeders anti-grav engines meant I didn’t need to worry about crashing into anything besides the occasional pile of Ork corpses, which would soon be cleaned up as the fortress advanced.
It wasn’t long before we saw the ranks of the Partinax, carving their way through the encroaching horde of Orks like a lasbolt through butter. Carefully placed shots, fists, and boots took out the biggest threats in the crowd first. It was obvious that they were headed towards the Ork’s Warboss, who was spraying a ceaseless hail of heavy bolter fire down from the hilltop, luckily with the usual Orkish lack of accuracy. The greenskin in question was large, even for a Warboss. It was roughly the same height as Big Obduratius himself.
