Existence is every dimension. While most anything is applicable, it'll be difficult to get interaction with other players without an understanding of how your character could possibly end up meeting them. For example, if you choose a regular character in some established universe, there'll be almost no way for them to run into the other characters in MR.

In other words, while the idea of a sandbox isn't strictly [i]in[/i]correct, it's still a sandbox that you're sharing with everyone else =)

Thank you for the clarification. So basically I should figure out what's going on in the IC currently, and make a character that will be able to participate in the situation? Since it seems like there could be multiple plotlines going on in different dimensions, I would assume making a character capable of dimensional travel would be ideal here.
