At level 60 every player can buy an Order of Justice at the Justice NPCs. Once you buy an Order at the NPC you can get a quest for the item from the same NPC. You can now choose what kind of mob you want to kill.
The Quest itself consists of three parts.
1 Kill the mob you choose
2 Let 60 minutes run by and then talk to the Envoy of Justice again.
3 Bring the Brocade Box you got in your quest inventory to the specified NPC
Once you finished all three parts you will get the reward.
