Although no players have gone there (yet), there are golems guarding a library located in the middle of what is now a desolate waste. They are absolutely motionless until a book is removed; they then track the book unerringly over any distance until the thief is killed, then they return the book to its rightful place in the collection.
The wizards who constructed this library perished long ago, and with them was lost the method to remove scrolls without triggering the guards. Also lost was the knowledge that such things even existed (I use a very narrow monster palette, which has the effect of enabling me to surprise my players with what are, for a normal campaign, rather normal foes).
