Which means, to my Castlevania inspired mind, my version of the Haunted Keep became the lair of a vampire. And it was broken up into several sub-sections, each with a sort of 'boss' encounter, and a place to magically rest and recharge (just like how Castlevania levels end with that orb dropping to recharge your health after you beat the boss). OK, maybe kinda lame, but the dungeon did have some pretty cool stuff in it, though.
Particularly, I'm fond of the castle's courtyard, which was a maze of semi-sentient thorn hedges. You could chop your way through or try to fly over them, but you'd take damage doing so.
Maybe I'll get ambitious and type up the notes to go with these maps and make it into a downloadable PDF. Don't think I'll have it done in time for Halloween this year, but oh well.
Then you had to go through the courtyard thorn maze.
Then you had to work your way through the crypts to get into the Keep.
Finally, you had the five levels of the Keep to deal with.
I remember that Killingmachine and I ran through this one night at his house. He played several of his PCs, and I ran several of mine to fill out the party. We had a blast, and I know we finally beat the vampire, and I don't think anyone got level drained too badly. :D
