They are these young girls with a special connection to the ADAM in Rapture. And of course, the protagonist, whose journey and actions drive much of the story forward.
In the 'Bioshock' full story, one key element is the concept of utopia turned dystopia. Rapture was meant to be a perfect place but ended up as a chaotic mess. The genetic modifications are also a big part. People's overuse of ADAM to change themselves led to the creation of splicers. The power dynamics between different groups in Rapture, like the Fontaine and Ryan factions, play a major role. And of course, the player's journey of exploration and survival within this strange world is an essential element.
