My own module that I am currently working on, is of my old tiefling character discovering an uncharted island and building her personalized keep (rp server). Meanwhile, two other previous PCs are running the local Thieves Guild, the docks are being hurriedly constructed for the arrival of nobles from Amn, and the new smith has been writing love letters to none other than the leader of this small, but humble city.
I've included some very odd things, whether it be the tavern in the north district, "The Three-Legged Hare," or the boatman's, well, boat, "The Lukewarm Mistress." Both names have come from suggestions from my crazy, though generous, friends.
All in all, I think making modules is incredibly entertaining, at least for me. Any of you think the same way?
