Hey ! 
After going through all of that info up top I can say I am interested, and have one or two concepts for characters in mind - and some questions!

You are going to be controlling some story-important characters and the like; am I to understand that we will be controlling mostly solo characters or does this RP have Nation-esque notions?

Also I had a question about these invitations sent far and wide; is it simply invitations to the island or are we (if invited) supposed to attend one big event towards the start of the story? I'm only asking because I want to think up stories that will lead to interactions with other players - not a big fan of aiming aimlessly by my lonesome. :P
