Right, so, we need the following elements in questing:
Flaming Skeletons
Man-eating spiders
A trip through <x cave>
A symbolic flying <insert something here, from frying pan to phoenix)
Demon. Obviously.
A run-in with brigands.
Quicksand.
Out-of-place trees.
If we have all these things integrated into the roleplay, than we shall have an adventure to best LOTR.
