[0] We are using very specific language here, as a single player might be running multiple copies of TaleSpire at the same time. Either from multiple computers or even just one.
If a single player joins the board from two separate running copies of TaleSpire, they will have two portraits. One for each client (copy of TaleSpire).
99% of the time, each player is only running one copy of TaleSpire, so it doesn't matter, but we wanted to be precise here.
