RaiderZ can be quite confusing early on because of it's use of Zoning meaning you can be standing right next to your friend, on the same server and channel but still not see each other. I think this is how it works early on. So when you first get into the game you'll be in lets say "Zone 1" and your together with other people who are in "Zone 1". You'll be in Zone 1 until "Natura Underground Sanctuary" you go into a Dungeon, after you exit the dungeon you put into "Zone 2". "Zone 2" is separate from "Zone 1", it's the same area but people in Zone 1 can't see people in Zone 2 etc. Zone 2 lasts until you beat "Crawler" in the main questline. After you beat Crawler you're put in yet another Zone (Zone 3) with everyone else that has beaten Crawler. Haven't been able to test this but I'm pretty sure the Zoning only applies to the starting area "Broken Mast" if you were to travel to the City right next door "Ingen Freeport" you should be in the same "Zone" regardless of the Zone you're in in Broken Mast. Just make sure you're on the right server and channel.
