This multiplayer scenario is based on the RuneScape activity Pest Control (see www.runescape.com). You must protect the Void Knights whilst fighting back hordes of enemy troops and destroying their portals which lye off the coast of the mainland.
There are four portals on the map, one to the North, East, South and West. Each of the portals is protected by a magical field and you will not be able to attack any portal until the Void Knights have been able to break down its defences. For this reason, you should do your upmost to keep the Void Knights alive until all of the portals can be attacked. You will be informed in your chat when the Void Knights have broken down one of the magical fields. The game will end when all the portals have been destroyed.
The Void Knights are devoted to keeping the balance that exists on Gielinor. In the past this meant little more than the odd assassination, but times are changing. Recently, enemies from another realm have begun breaking through into this one, although these incursions have so far been limited to small islands off the cost of Gielinor.
Outposts were constructed near the regular breaches to house the Void Knights whose magic was used to close the portals. Unfortunately, the invaders have become more aggressive and have managed to overrun some outposts before the ritual could be completed. You must help the Void Knights' efforts and fight back against the enemy!
