I was up around 3:00AM thinking about the possible bachelor party adventure. Many of my original thoughts were things that happened to and around the players, plots basically. But I know the trouble that lies that way. So I've revised my thinking, this needs to be a location.
Grognardia's post the other day about funny names gave me an idea. See, I've long been one of those folks who've cringed at anything that didn't take the game seriously enough. But I'm revising my views as I see that players can take a game very seriously even if it has silly elements. So, I started with my friends name, Marcus and came up with Mah-kuss the Eternal Bridegroom. And immediately I started thinking of things that would amuse my friends: He of the 12 Titles, He of the 665 Brides, Mah-Kuss - the Tumescent Shadow, Mah-Kuss the Turgid, He Who Would Eat His Young if He Had Any, etc.
I'm currently imagining a ziggurat built in the forgotten past to honor this god/demon and his many brides. Inhabited by a albino, round-eyed, tribe of worshippers. (The groom and I were just talking about how 99% of fantasy badies are dark-skinned, so I'll buck the trend here). And at the base of the ziggurat's interior an avatar of Mah-Kuss which is a huge, bloated, albino worm- similar to a purple worm, except the posionous stinger is an eye that petrifies.
I was also thinking about building in references to the players, although that would be easier if it was switched to a female demon with hundreds of statues of her grooms, hmmm . . . Maybe his groomsmen can have statues and I'll give them imperious names and have them look similar to the players.
As far has things happening, I do still envision the start of play is that all these characters are escorting a small party of women to deliver a gift to Mah-Kuss. And these women then jump with their gifts happily to their deaths into the bowels of the ziggurat. If I make the treasures they jump with enticing enough, there should be plenty of reason to search for a way in to try and retrieve the goodies.
Random sidenote. I have an idea for a golden bowl that the players discover somehow which, when its cover is lifted reveals a somewhat gruesome lipless mouth set in flesh. This mouth will make proclomations and answer questions in confusing and problematic ways. Yeah, that interests me.
