Took 's idea of using

They are lined up in some kind of order.
We've got
The Original heroes: Three newcomers living the simple life.
The Timids: Two students who are mature but not loud.
The Siblings: Three family members who seek a new start.
The Gypsies: A Psychology teacher and an adopted young girl.
The Unnatural: Two students and a teacher who are weirder then they appear.
