With Games Workshop focusing solely on Imperial Terrain it falls to independent modelers to create Xenos terrain, or to convert it up ourselves... or both at the same time. Recently I completed work on a Bastion themed for Eldar.
Quite a while ago I had been frustrated by always battling on Imperial worlds and I had sought to adapt my board to an Eldar Maiden World. I had completed that task, but then I moved across the world leaving my board and terrain behind. Now comes the slow board building process again, so that once again I can protect a maiden world, and avoid always gaming on a bleak Imperial Colony. Maybe this time I can convince myself to go all out with some of the ideas I've been fostering for a while.
Using a kit from Miniature Scenery I was able add on some left over bits and conversion parts to make something that was both fitting for the rules and suitable as a comparative model.
While the top section can only hold about 7 or 8 models a large squad can spread along the outer steps, though this would make it easier for opponents to assault the unit.
That's a Wraithknight for size comparison purposes, though that model is tall enough to play King Kong and just reach out to pull models off the top.
The entrance is made from a spare hatch to a Falcon. The troop compartment is made from an old bottle that I cut up and is actually larger than the rear of a Wave Serpent, so, like the serpent it has a 12 model capacity, compared to the standard 10 for bastions, but doesn't have any Fire Points. It seemed like a fair exchange.
Rather than Heavy Bolters to all four sides, it has thematically appropriate Starcannons, 2 facing the front and 2 the rear.
Hope that inspires people to work out their own take on Xenos Terrain.
