If you're planning on logging into the Dark Age of Camelot test server, Pendragon, and find that you are unable to do so, fear not, if you are currently running the Trials of Atlantis client then your problem can be easily fixed.
Heads up! Pendragon [is being brought down] in order to disable the Trials of Atlantis client and for related code adjustments . This is in preparation for the removal of the client from Live servers when 1.91 goes live. If you currently use the Trials of Atlantis client and plan to log into Pendragon ... then download the Catacombs client.
You can download the Catacombs client for free here.
