This is intentionally presented with little preamble. The set up is as follows: the players enter any location, such as a tavern, an inn, a shop or any similar location, and find there several casualties, all badly wounded. One will mistake a random player for a friend, and will begin babbling that the players must "stop the invaders" and that they "went through the downstairs door." If the players go downstairs, they will not find any door in the cellar ... but a search for a hidden door will automatically reveal one. This will lead the players into the top left of the map.
Additional information should be something the DM can add - such as how to close the open gate and so on, which can be done by hand or a lever. The dungeon description is intended as a guideline which the DM can elaborate upon. I will, however, add additional material as it occurs to me.
- The straps are loose. No weight is hanging upon them, and they can be pulled up for use by the players.
- The boy's name is Uthor. He knows nothing of the concealed door at the end of the library; he did not know it was there, as it was plastered into the wall. He also knows nothing of the level reached through this door.
