First ESO Adventure Zone Revealed -- Craglorn — April 7, 2014

ZeniMax Online Studios is wasting no time in producing new content for the newest Elder Scrolls game, The Elder Scrolls Online. Players of ESO will now be given the opportunity to explore Craglorn, a mysterious place where the constellations have disappeared from the sky, and new beings called celestials, taking the names of the traditional constellations, have appeared in their absence. The new content is specifically tailored for four-player groups at veteran rank ten. Additionally, new player versus environment challenges, called Trials, will also be included.

While there is no current release date, the update can be expected to be added into The Elder Scrolls Online soon.
