Every player gets a unique index upon entering a level. Graal is smart enough to be able to keep it ordered somehow (chronologically perhaps?). Clientside, 0 refers to whoever is currently using it. Serverside, I believe 0 refers to the last person to affect it, don't quote me on that. Other than that, everyone has a natural number index

Say you and I are in the same room. One of us would have index 1, the other would have index 2.
