To represent this rampage, thus began the Necropolis Campaign, kicked off by a battle between the Necron Fleet and a quickly assembled force of Eldar.
For this battle and the ones to follow, the Necropolis needed a suitable model. After gaining some experience scratchbuilding the Vulture Class Cruiser, I wanted to try something bigger, and the Necropolis was it. Being made of simple geometric shapes, etc., Necrons vessels aren't too hard to scratchbuild. I built the entire thing out of plasticard and some clear tubing (made by a plasticard company named Plastruct).
I debated for a while on what the ship should actually look like, and ideas like a huge pyramid passed through my mind, although that seemed almost too Borg-like. Eventually I settled on designing the ship around one of the most common Necron Symbols--nothing says "Necron" as much as a ship that looks like one of their icons! The "hole" in the center of the ship serves a dual purpose--I envisioned it as a portal of sorts that could teleport in Necron escort ships--and what do you know, a Jackal escort fits perfectly within it! (I designed it that way)
I painted the ship in the standard necron metallic colors, with a stepped pyramid aft painted in the metallic blue that is the color of Badelaire's Necron forces (q.v. the Tombworld Beacon)
