[@mattmanganon] Hey there! So currently while we are in the middle of a story arc that would allow for someone to join during it, not exactly in that specific manner, since everyone is currently in space, but because of where in space they are, it would be possible for others to join right now, just wouldn't involve being at the mansion or going along that way. As for age, we have people ranging from 18-31 character wise, and the majority of them are 20 or older, so they aren't really teenagers (some of them started off as such over the time in the RP though) and we are fine with them being of any age. There might be a way to still make that concept kind of work out, just might have to alter a few different things to have it work and bring them in in the middle of the arc.
