It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, In the morning, while everyone else is taking breakfast, Pike checks the front door and finds about 20 skeletons waiting outside. She and Grog charge out to handle them.
DM: All righty. Indeed, what looked like two different hallways was one entrance to the chamber that was divided by a singular column in the center. You both flank around as it opens up inside. You see a 50-foot-tall, 70-foot-wide natural cavern chamber that rounds out over the top, and you see it end on the opposite side. There are two pillars nearer to your end that both hold defaced statues of a woman on each. Defaced statues of a woman. Partially destroyed and collapsed. There are elements of it broken on the ground. The heads removed. In the center of the chamber, you see before you a massive stone-stepped pyramid, similar to the ziggurat you've found. The design is a little different, and you get the sense that a lot of it is still buried and it's just the top that has been uncovered and repurposed for whatever this may be. You do see, there are a number of cloaked figures scattered across these steps, and some of them are out looking in your direction as soon as you come around the side. They're all wearing the same black outfits, the cloaks. Some of them have the hoods back; some of them have the hoods on. Roughly, you have what looks to be six or seven from what you can view. There are two of them at the very top that currently have what looks like another crate that has been opened, and there above them, you can see the black orb, exactly like the one you have underneath Whitestone, and they're in the process of taking objects out and throwing them up into the sphere, and you watch as they flash and vanish into the darkness. You see one cloaked figure that's currently shouting out and giving commands right now.
Player: Do they see us?
DM: With all of your stealth? You got a 19, correct? One of them shouts out, "We have visitors!"
Player: Do they only see that side? Do they see us come around the other side of the pillar? They see all of us.
DM: As soon as they all glance over, you guys are out in the open of a hallway. Once they see him, they see the spread of you. As this happens, you watch as a number of skeletons walk out from the halls on the sides, and one seems to suddenly shake and rise up from the ground: a large skeleton with what looks like giant horns that curve out of the head, standing about 12 feet tall. Looks to be some sort of minotaur-like beast, but bone and anger.
Player: How far away is the ziggurat?
DM: The ziggurat from you guys? Let's pull out a map. (cheering)
