The first encounter consists entirely of British people awkwardly opening doors, finding others engaged in marginally compromising situations, and then apologizing profusely at the inconvenience they've caused as they try to back away.
I know it's an experimental design, but after the first 7 or 8 hours, I think the players will really get into the style and mood of the campaign.
You could lay it out like a Choose Your Own Adventure, with the description of what's behind each door being on another page, printed upside down in small type. "Basil timorously opened the iron-banded oak door, and averted his eyes from the scene before him. To find out what he saw, turn to page 34 and invert your PDF reader." Choose a font to match the feel of the story, preferably one with lots of flourishes, ligatures, and mystical symbols replacing some of the letters. When printed at 8 point size, just deciphering it will be an adventure in itself! Enhance the feel by using low contrast type over a grungy grey speckled background with a watermarked image. It'll be just like those great captcha mini-games you find on websites!
