It is planned closer to the end, what do you mean by reunite ?
well at somepoint you died and I guess you have to reunite everyone to take on the main enemies. am I wrong?
Oh, well it's part of the story, can't tell anything yet otherwise it would be spoilers !
but yeah overall you're right !
I have a basic idea after you died but thanks for confirming that much and love the game keep it up but don't stress too much just keep a nice smooth pace
