Well, anything beyond 350 on the map, in the + or - is a pvp zone, aside from town halls. So, there's a very good chance that if you see someone out here, they'll probably try to kill you. It's nothing personal, people just tend to... well, die, here. A lot. Speaking of that, mobs here can be pretty vicious. At low levels, you can't expect to be able to kill them by just yourself. It's best to party up with others.
Look for a town as soon as you can! It gives you people that can help you out, and a relatively safe place to hang out. New towns are almost always looking for members to get their required number of citizens, so asking around on "/ch re" (channel recruitment), you can find a town usually with ease.
