Warner Brothers Interactive and Wizards of the Coast have officially opened the floodgates on the latest expansion to Dungeons and Dragons Online, The Shadowfell Conspiracy. Shadowfell features a dragon's horde of exciting additions. Foremost among these are two new adventure packs which challenge players with infiltrating the prison city of Wheloon and dismantling a Netherese secret weapon deep within the reaches of the Stormhorn Mountains.
