Why Do We Always Have To Go To The Basement - Maid Of Sker Episode 2

I don't like the fact that this place has so many doors leading to who knows where. Why do we always have to go into the basement. And what was that thing? I couldn't help that one guy, Henry, but Elisabeth is right. I gotta keep to myself. Gotta find those cylinders. But where are they? And why am I outside now? I'm so confused.
