Pictures, maps, descriptions?

Whats there? How do you get there, whats the layout? How large is it, etc etc. My players will be going there soon, and I would rather not have to come up with everything myself (cause I'm lazy)

According to one of the short stories, Bastion Serpentis has a massive library containing information about the Tyrant Star. However, Lord Inquisitor Zerbe tightly controls access to it and even if an Inquisitor can gain access, they must ingest a poison that will kill them in one hour unless they return to the entrance and drink the antidote.

I think that's not always the case, I'd bet the members of the Tyrantine Cabal have free access to the library without the poison thing (I'd also guess it's not actually poison, but something more... unique). It's not just a library either, it's also a moderately large complex used by the cabal and their associates for logistics, training, and just getting away from the masses (though more in a plan and reflect sense, than anything vacation-like). Data terminals, cogitators, a number of tools and resources are all available to the Inquisitors and acolytes trusted and used by the cabal. The rest use the Tricorn facility from what I understand, which is more conveniently located anyway (as the Bastion is on one of the moons).
