On April 5, 2006, Turbine opens the door to the Dragon's Vault, the first content module for DUNGEONS & DRAGONS ONLINE™: Stormreach™! The Dragon's Vault module will provide players the opportunity to battle the dangerous Vault of Night that is protected by a ferocious guardian – a red dragon in a large-scale raid encounter, as well as 15 other compelling new dungeons.
To release this module, we will be bringing the game servers down from 7AM to 2 PM Eastern on Wednesday, April 5. You can preview the contents of this module on our forums.
