I'll update the decoded qr codes with the order:
1 - You pass through two large iron doors into a large chamber. There are magical symbols inscribed on the walls. A strange mechanical sculpture of rusted gears and pipes dominates the space of the room. Beneath the sculpture is a vent emitting hot steam.
2 - You nearly fall into a pit of deadly iron spikes. You see a shadowy figure in your peripheral, but when you turn to look, no one is there.
3 - The corridor is lined with pulsating light bulbs in iron sconces. In an alcove there is a fallen statue with an inscription “When azoth and fire whiten Latona, Diana comes unclothed.”
4 - A corridor is before you. There is a dim flickering bulb at the end of the corridor. You're not sure if it's your eyes adjusting to the low light or if you see a shadowy figure wavering in the distance.
5 - In a small damp room there are metal gears exposed in the eroding floor. The gears are rusted and beyond repair. A clanking sound can be faintly heard in the distance. Someone has scrawled “He who can burn with water and wash with fire makes a heaven of earth and a precious earth of heaven.”
6 - Skeletons hang from chains and manacles against the walls. The floor is covered with iron gears, rusted scrap metal, and empty glass vials. You discover a leather jacket.
7 - An iron chandelier hangs from the ceiling here. There is a bookcase, you discover it pivots smoothly and reveals a secret door. In the small secret room there is a book lying open on an iron podium. The book is titled "Mechanica Mathematica," there are pages torn out.
8 - The walls have been engraved with geometric patterns. An iron altar sits in the corner of the room with an inscription “If you make the earth fly upside down, with its wings you may convert torrential waters to stone.”
9- You are in a rusted iron chamber. Water is trickling from large iron pipes above you. On the wall someone has scrawled “When in your house black crows give birth to white doves, then you will be called wise
10 - There is an iron passageway, it is very dark, you walk slowly with your hand against the wall guiding you... just in case. You come across a fortified iron door guarded by two mechanical gargoyles. There is an inscription on the door “The dragon guards the key.”
11 -

There is an opening to a large sewage pipe, the grate has been removed, you think you can crawl inside. There is an iron chest with a scroll that reads “It is the secret deed of the true sage to open the earth, so to make salvation germinate for the people.” Also inside the chest is an iron knife.
13 - You are in a large chamber, there is a domed ceiling above you. An iron sarcophagus sits in the center of the room with an inscription that reads “SI SEDES NON IS.”
14 - You are in an iron chamber. There are strange mechanical devices strewn about the room. It is dusty and the air is stale. On the wall someone has scrawled “The diameter of the sphere, the tau in the circle, and the cross of the globe bring no joy to the blind.”
15 - Water surges out of a large pipe and begins to fill an iron chamber. You brace yourself against the wall as you find yourself knee deep in a channel of rushing water
