Sony Online Entertainment announces the City of Brass has opened its virtual gates as part of the first content update for Vanguard: Saga of Heroes since the MMORPG went free-to-play. The Vanguard Website has details on the expansion, and here's a bit:

In this update, the Efreeti have returned and are imprisoning mortals beneath the fiery skies of Jhor Razkur, otherwise known as The City of Brass. Players are invited to join the fight against the Efreeti and their allies inside the City of Brass in this all-new adventure area.

The new City of Brass area can be accessed beyond the eastern walls of Khal. Users will face off against more than a dozen challenging named and boss mobs, earning valuable new loot. Daring souls who best these foes may summon forth The Keeper of Lesser Wishes, a 12-person encounter that is sure to test their strength.
