Rift will be getting a hefty update on July 19th with the arrival of the Celestial Storm. It will feature a new zone complete with quests, the Tartaric Depths in normal mode, new raid rifts, a new instant adventure, new creatures and four new Primalist Souls. If that's not enough to get your attention, perhaps the news that the Prophecy of Ahnket expansion is now free and will be forever.
The Rift site has a nice lore preview of the new content, so head on over for a look.
Thanks for the tip, Forgrimm!
