The room they find themseves is circular and cillindrical, though it has a semi-spherical cupula atop it, on the very apex of it a big turret looks down on them, it seems to be deactivated, probably for the best of the soldiers that stand there, else they'd already be being shredded.
It is notable that there are many doors within this room, going from left to right, there is a single closed door that appears big enough for one person to fit through, and two larger closed doors, these appear to be more heavy duty, still nothing compared to the door in the first entrance, but they'd take some minutes to bust through, a mild nuisance one'd say. Each single one of these doors has some strange, undecipharable writing that seems to glow a dim red, as to still be seen with clarity even in the dark lighting of the room.
Again to the right, a massive door, this one appears to put the entrance door to shame, maybe with a full-sized ship it'd take weeks to dig through that ammount of metal, so for now anyone sensible'd judge that it should stay as it is, closed.
Lastly, a low wind howls from a corridor that connects to the cillindrical room, though this corridor gives away to a staicase of consistent steps but slightly warped sides, the black-ish metal slightly cintilating on the very end of it, which is lilluminated, it seems to go to another floor that has much better lightning than the one they are in right now. No doors stand on their way.
(Btw it's okay busting through doors, though I don't recommend it cus it takes time.)
