Need help defining where pvp is allowed and not allowed

I need help making my server. So what I need help on is where my server spawn is non-pvp and outside it is pvp. Here is a picture to show you what I mean. I either need help doing it or recommend me a plugin to do it.

 

I'm assuming this is Factions?

1. In your server.properties file, make sure PvP is set to true.
2. Select the Region you want with //wand.
3. Do /rg define <region-name>.
4. Do /rg flag <region-name> pvp deny.
Some other useful flags for spawn are: Build: Deny, mob-damage: deny, entity-item-frame-destroy: deny, entity-painting-destroy: deny. These are just a few of MANY you would want to have for spawn. Check out http://wiki.sk89q.com/wiki/WorldGuard/Regions/Flags for all the flags worldguard has. For spawn, you probably want to deny most of them, but that's your choice.

When I do world guard it is a square. But when I already have a region define on my spawn, the other part that I want pvp is over-lapping it. Is there a possible way to create a world guard define that is not in a square.

 

You could possibly just get a region with a straight line. It's hard to explain but make a region up top and then make one down below.

Wait if my regions over lap will they negate each other?
