"Beyond here, there be dragons" is a classic warning, and it applies to the vast majority (if not all) successful stories and screenplays today.
This is an important and often elaborated element of the Hero's Journey (Monomyth), and it often occurs before the Crossing into the First Threshold. It is separate and distinct from the earlier Interdictions.
In Dances with Wolves (1990), John Dunbar is warned not to go to the frontier and then warned not to engage with the Indians.
In The Matrix (1999), Neo is warned before entering the room to meet Morpheus and before taking the red and blue pills.
In Gladiator (2000), Maximus is warned about engaging Commodus, the Emperor of Rome.
In Star Wars (1977), Obi Wan warns Luke before they enter Mos Isley.
