Thunderdome was moved to another position because of it being in a rather stupid position when it comes to re-spawning, We have a new more practical arena in the hub region and there's also the option for Khan members to play "Meng town" which is our latest arena. The Loot that you captured from our former Arena is Indeed Plundered equipment that isn't in any way essential to our Organisations activities and is one of many former occupied territories in our Dominion.
Please stay tuned for the release of our new Arena which was announced via Khanscentral forum well before the old arena was "infiltrated".
