For purposes of CNRP, your IG nation does not even, necessarily, exist. While character RP's don't require much, to RP as a larger recognized, sovereign entity, you have to first either claim white land, or talk to the person who owns the land you want, and work it out with them. many people are willing to give up portions of their land to a new player, to encourage new nations to form.
Others will require you to go through less independed phase, such as a protectorate or simply semi-autonomous zone.
Some won't give an inch.
But you won't know until you actually PM them. You don't get to RP anything at ALL in someone else's territory without their permission first. In this case, the person you need to talk to is Voodo Nova.
As for how your IG nation relates to here...it can be RP'd as any of the above, once you have the go-ahead. It's your choice, within the restrictions set up by whoever gave you the permission.
