Wizards of the Coast has launched War of Everlasting Darkness, the final D&D Encounters season for Rise of the Underdark.  The new season of the Dungeons & Dragons organized play program offers three new features: characters can level up at the end of each session, and will progress from level 1 to 8; players will have more character options to choose from, drawn from six different books; and each session will be more like a mini-adventure than an encounter.  The War of Everlasting Darkness season will run through December 19th. 
Rise of the Underdark has been running across Dungeons and Dragons platforms since Spring (see "'Rise of the Underdark'").
