1. The first, faint glimmerings of an idea or two that perhaps swirl around in your head and breed together and you think... yeah, that might be something...
2. You commit! Volunteer for something with a deadline! Everything will be great! The ideas are just bubbling up and it's going to be awesome!
3. ... Then the timer starts ticking down...
4. You remember how wonderful it is to have friends and loved ones who provide moral support, remind you to sleep regularly, help you when your computer dies-and-it's-the-last-week-and-there's-stuff-still-unwritten-and-aargh...
5. That last week of running around screaming because! deadline!
5a. That odd floaty feeling when you actually get everything finished including printing a solid two days before showtime. This was actually rather unfamiliar for me, but since I was visiting my sister before KapCon I rather needed stuff done. I cuddled her baby and drifted.
6. "Oh my god, what was I even thinking, the execution is flawed, and the concept itself is... " Alas, this stage is very familiar.
7. Show time. I set up the room for my larp The Face of Oblivion with time to spare. There were cute posters about kakapo (and if you don't think horny flightless parrots have anything to do with habitats in space and DOOM! well, I guess this larp has some things of interest for you :) )
7a. People get their character sheets and there is dead silence for five whole minutes and I revisit Stage 6... And then the players start quietly talking and the group dynamic forms and the tension ramps up and... wow.
8. End of game. Everybody really needs a hug.
9. Apparently, word of mouth is good enough to get the second run booked solid. Yayy!
tl;dr I ran a larp called The Face of Oblivion at KapCon; it went well. The rest of the convention was wonderful.
