I think I've got something that works. Here's the elevator pitch:
When the Enteri faced extinction, they built an ark that would allow their species to survive. Scientists and pacifists by nature, they created a legion of bots to assist in the creation of this. Within their tallest peak, they built a massive laboratory that would survive their planet's collapse. It worked, and they spent decades floating in space, gather all manner of flora and fauna for preservation. However, their bots became corrupted and turned on them. Now, mad bots patrol its halls, strange creatures break from their binds, and the last remnants of the Enteri hide in the deep recesses of the complex, struggling for survival.
I liked how work was going on material for Hack'D & Slash'D (with having a living online document as support), meaning that you can watch the design process in real time, if that's your jam.
