To lead my Dark Eldar into the apocalypse I have added the current matriarch of the Depravum family to my army: Empress Lethis Depravum. She goes to battle with her own wytch cult; the Cult of Ecstatic Fear which I have recently bought the first unit of. I have also created a huge monstrosity to use as a Dark Eldar Super-heavy unit.
My Dark Eldar only reach just over 2000 points but I thought it would be fun to create a super-heavy for them to use in apocalypse games. All conversions for such I have seen so far are simply repurposed Eldar titans or really big raiders. I decided to go a different route and create what is essentially a large Cronos Parasite Engine. In the background the Haemonculi regenerate fallen dark eldar in their laboratories, I thought it would be interesting to have a mobile regeneration unit that uses the souls of those slain on the battlefield to restore a dark eldar lord and empower him. I therefore created this monstrosity.
