The woman looks around the room. "Well, it appears all of you are here; I suppose he will." She steps out of the room, closing the door behind her. For a moment, there is silence.
"Welcome." It's a deep, masculine-sounding voice, with no apparent source. "Thank you all for joining me today. I understand my letter was vague; and necessarily so. This isn't something that I want to be spread across the city. But I assure you, your presence here will be worthwhile. For I wish to share something with you. I cannot express how excited I am, to finally begin revealing my discoveries with the world around me. For generations, humanity has dreamt about making a discovery... ah, I apologize; I have a tendency to be long-winded."
"I have chosen you to be some of the first to travel to a world beyond our own." He pauses for a moment to let that sink in. "This is not a hoax. Nor, as far as I know, is it a conspiracy. No secret organizations shall be hunting you down for what you've learned today. In all honesty, there are very few strings attached."
"My request of you is simple: step through the door in the far corner of the room. Meet with my associates on the far side, and experience all of the wonder that such an opportunity presents. Once you've had your fill, return through the door and tell me of what you've experienced. You will be free to make multiple journeys, if you so desire, or you may leave it at one. But would I be correct in assuming that none of you could walk away without experiencing this at least once?" The question hangs in the air.
