Faction API Help

hello, im having problems with something that sounds very simple.
what im trying to do is check if a faction is in a certain location. if it is not then 'return true'
this is the code i tried using;

Code:

            Location location = new Location(Bukkit.getWorld(world), X, Y, Z);
            Faction faction = BoardColls.get().getFactionAt(PS.valueOf(location));
            Faction wilderness = FactionColls.get().getForUniverse(world).getNone();
            if (wilderness == faction) {
              return true;
            }

this code does not work, can someone tell me why and how to make it work. Thanks

sorry i meant if the location is equal to the faction land 'wilderness' then return true
