The players investigate an abandoned research station that contains a few eccentric inhabitants. The players eventually realise these people are all the same person who went crazy from isolation and developed multiple personality disorder and the other personalities resleeved themselves into other morphs. The players must find them all and get them back into the same morph one way or another.

A prophet emerges and calls for brave souls of Transhumanity to accompany him through one of the one way Pandora Gates on a quest to settle upon a new homeworld suited to humanity's needs. He promises that he knows that if they go through this gate, they will find one. He's managed to attract a following of dreamers who crave a welcoming planet to call home and are starry eyed with dreams of pre-fall Earth. The Firewall team in your game is assigned to support his efforts under the theory that another colony can only increase Transhumanity's survival chance. Plots could involve preventing assassinations against this Prophet, helping him gain access to the Pandora's Gate itself, or joining his crusade as the people who will bring along the technology required for resleeving, making him dependent on them.

An intro scenario: "Surrounded by Zeroes." The PCs are a bunch of agents tasked with (or undertaking on their own initiative) rescuing a freighterload of zeroes from indent at the hands of ultimates and delivering them to somewhere safe (the Jovian Junta will at least get them meshed and basic-biomodded properly, and flats are still better off there than in Ultimate hands; if you know your players have a knee-jerk hate for the Jovians and won't do this, they can learn that Titania's got room or that Morningstar is looking for new recruits). Sounds fine, right? When the players get to the freighter, the GM can play the flats as moderately-retarded adults who can barely understand half of what they're saying, don't understand them at first since they don't have any translator software (the PCs can probably solve this once one realizes the problem of course) generally have no useful skills (their idea of "expert professional" is something a well-programmed AI can do), and haven't got the wit to take anything humorously or non-literally. Even the muses are smarter. Can the PCs take control of the freighter without one of the zeroes trying to help and blowing the whole operation? Can their sanity withstand the effort of dealing with the zeroes? Can their ethics withstand a chance to take advantage of the poor saps (who they could convince to do almost anything)? --- Yes, I just described how ordinary modern humans would look to post-Fall transhumans.

"Celestial Chorus" The characters are gathered on a small hab in the Main Belt to investigate a sound file that has been making it's way around the habs mesh. The sound is described as thousands of human voices singing in perfect harmony. The song has no lyrics, it is only a wordless chant, but it speaks of keening loss and a vast loneliness. Their Proxy doesn't let them hear the file due to the fact that on closer examination of the song, it translates into and extremely complex program, one that changes any mind in comes into contact when. This program is beyond the capabilities of transhumanity to produce. The song is being labeld the first Siren Hack, kin to a basilisk, only aural instead of visual. Investigation of the residents of the hab find that those exposed to the song show Borderline Personality Disorder, as well as an encouraged need for the company of others, and a boosted need to expose others to the song. The characters will trace the song (hopefully without getting exposed) to a freighter pilot docked at the hab who claims to have picked up the transmission heading through an empty part of the Main Belt. Firewall records will show that that area used to have a research hab that was supposedly destroyed during the fall. Sent to check it out, the characters find an abandoned hab, battle scarred on the inside, with a single massive databank. This databank contains thousands of Infugees, egocast here during the fall. However, the databank shows signs of TITAN tampering, and the infugees have been half-melded into a kind of collective hive AGI, one intent on easing it's loneliness by absorbing as many egos as possible, even if forcibly. This is the purpose of the Siren hack, to prepare an ego for absorption. As the characters study the problem, probably to find a way to reverse the effects of the hack, a new vessel docks and the characters are attacked by a group of people intent on merging with the AGI. Sorry, long, but hopefully it will help to generate some ideas.
