I love the theming and creativity- I think the PDF didn't upload right. Rooms in the basement are referenced, but there is no page detailing the basement's rooms (where the control room is, and where I presume the Sigil is?). I instead see the intro page, the first floor, and then the same page (The Yaksha's reward and the Appendix) twice for the last two pages. I hope it was just an upload error, easily fixed!
