The Riders of Icarus site has been updated with an extensive patch note list to detail the Exarahn Badlands update that has been deployed on game servers. Players can now take part in the Exarahn Badlands PvP zone including Manastone Battles and all attendant events.
Riders can now travel back in time to a realm where no laws existed and chaos was rampant. Upon stepping through a newly discovered dimensional gate, Riders will find themselves 1,000 years in the past in a region once known as the Exarahn Badlands. In addition to new quests, new enemies and new familiars to capture and tame, the Exarahn Badlands is also an active PvP region. Enter and adventure at your own risk.
In addition, the patch notes detail current feature alterations and the addition of several new ones and lays out a list of known issues.
