Update 2.4 has a lot of "new" to it: a new planet (well, moon), new missions, new operations, new PvP options, new gear sets, new warzone maps, and new mounts. The update title refers to the Dread Masters who have taken up residence on the moon or Oricon, where a story mission series will allow players to further delve into the histories behind these happy-go-lucky folks. At the end of all this are challenging level-55 operations called the Dread Fortress and the Dread Palance.
