The Hunt

The players are level 5 and are about to be hunted by fae for The Hunt. The plan is to have them in an enclosed space using the chase mechanics in the DMG with the urban obstacles random encounter table, but I don't know if I should make them last a certain amount of rounds or have them search for objects that will make them 'safe'. And if so how to go about doing that.

I fell victim to having a fun idea with no idea on how to run it 🙃
