I ran a D&D session for my family (dad, aunt, uncle, cousin's husband) last Sunday. It was my first time bringing the group back to my homebrew world / plot after two years in the feywild.
They were in a hedge maze and found an intact redwood desk on clean white tiles... and that's all I had in my notes.
I scrambled and came up with a hidden drawer with a needle trap. And in the drawer would be a quill pen, a single sheet of parchment, and a bottle of ink.
The parchment showed as a letter addressed to the one who found it, but everyone else saw it as blank. At first they assumed this was an effect from the needle trap
However, closing and reopening the drawer refills with a new parchment, which behaves the same even if the person taking the parchment was not hit by the trap.
They played with it for 20 minutes, discovered that the bottle of ink was a magical potion, and moved on.
Then they discovered the minotaur in the maze, which was a callback to the game my Dad ran for our family when I was very young.
