I promise to write something about this two parter. Until then, I leave you with this thought: is there something a little bit silly about two people on the edge of a massive, frozen army being able to trigger sensor lights that go on forever? Or is it actually perfectly sensible and good OHS when designing a system to keep you safe for millennia?
And: are there massive chambers full of every occupation that the homo reptilia society pursued? Is there another area somewhere full of scale-groomers?
