Witchaven II: Blood Vengeance/Level 6: Stronghold of Chaos

Right at the beginning, you're stranded on a platform in the middle of a lava pool. Use your fire resistance potion if you have one; if you don't you'll have to suffer some pain as you hurry out of this room. There are no goodies in this starting chamber either, so don't waste your time searching it.

Now there are a few places you could go. The pathway to the pentagram isn't locked, but the exit door is, and they key to there is locked in as well, so first head to the eastern roadway of the fortress. On the north wall is a big wooden door; pull the chain by it to open it. Through the room full of imps is a door to a smaller room containing the brass key.

Now that you have the key, head to the northwest section of the castle and collect both the pentagram on the altar-like structure, and also the black key that's just upstairs from it through the brass key door. Head back to the center and from there into the southwest part of the castle, upstairs and through one of the black key doors. Pull the chain to lower that huge, ominous-looking door, behind which you find nothing but a couple of Mino Drakes and the exit pad.

Tips and secrets:
 * When you exit the first room, crawl into the passage in the outer wall to find some goodies, including an ankh, plate armor and some spells.
 * The narrow passage on the outer western wall of the map can be reached by flying. You will find a hoard of gold at the end of it.
 * In the northeastern quadrant of the castle is some sort of satanic shrine. Find an ankh amongst the goblets on the table. Although it might appear that there's a connection between this area and the brass key room, there's no mechanism to make it open. The red "door" is also a fake.
