any help wanted

I'm very interested in a RP about several nobles living, dying, and starting drama in a large, fancy manor in a strange (slightly fantastical) world. Would anyone else be interested in this? I'm super open to any ideas for plot, NPCs, or anything else.

How do y'all plot RPs? I've only recently started hosting (Is that the right word?) RPs, and I've been having trouble figuring out how to do it in any way that seems to work. I have had some experience as a DM for a DnD campaign if that helps.
