Three NPCs aboard the wreck of the ship Endeavor showcase what appear to be new Storm Legion soul names. These fine folk have the labels of Tempest, Defiler, and Tactician. A fourth NPC stands among them with the Harbinger title, which has already been confirmed as a soul for the expansion. The new names match up with hints dropped on the RIFT forums regarding the names of new soul trees. It isn't super official yet, but a new Warrior soul called Tempest, a Cleric soul called Defiler, and a Tactician soul for Rogues seem to all be safe bets.
In addition to the delectable new soul teases, the PTS update brought in Tempest Rising, a new world event which introduces the awakening of Crucia. Players will evidently need to fight off Storm Legion baddies, spread the word of the Storm Legion's arrival, and otherwise make ready for the oncoming storm.
