About 3 years ago I ran off a bunch of Dyson-style hand drawn maps. I was following his website and it inspired me to try out a few myself.
Below is one that never got elaborated upon. Secret Ways, is a hidden cave with a concealed bandit lair and in turn a secret crypt of undead. So the bandits are hiding behind a concealed door in some natural caves and unbeknownst to them there is a secret door in their hide-out that leads to an ancient crypt that has undead inhabitants.

The map is usable as a one session encounter in almost any Fantasy game system so it might make an appearance in one of my campaigns at some time.
