The World of Warcraft dev team has posted a new blog entry giving readers a peek at Patch 4.1 and a content preview called Rise of the Zandalari. The article gives lore beind the Zandalari as well as some information about locations and a lot more.
In years past, the Zandalar tribe, encompassing the wise and scholarly progenitors of the trolls, heroically assisted the Horde and the Alliance with thwarting the nefarious activities of their brethren in Zul'Gurub and Zul'Drak. Yet the chaos unleashed by the recent Cataclysm has reshaped the Zandalari's philosophy about the world and the dwindling remnants of their race. Led by a mysterious prophet known only as Zul, the Zandalari have issued a call to Azeroth's embattled troll populations: unite into a single mighty empire and save their race from extinction.
