Fire?
The 5 guards were shocked, seeing the thick smoke seep into the hall from the long winding entrance hallway.
"Quickly! Water? Water! We need water!"
"Yes!" They all responded, dashing into the only storage compartment in the wing.
That's right.
Because this was a guest wing, out of the many rooms, one was used for storing goods that were explicitly used in the wing.
Bedsheets, pillowcases, new and unused sponges for wiping themselves after pooping, and even spare buckets were all kept there.
And whether there were guests here or not, the two 5-feet tall massive drums of water always had some level of water in them. The servants would carry buckets of water from below and fill the drum whenever they saw the water in there running low.
Again, when guests weren't staying here, they would use this water to mop the entire floors and everything else in the wing.
