Reminiscent of early Dungeons & Dragons lore, Neverwinter: Strongholds empowers guilds to reclaim a keep and its surrounding areas that have been overrun by the wild. As the lands are cleared, guilds will build defenses both in and around their strongholds using structures like barracks and additional troops armed to protect the keep. Once the keep has been secured, guilds will have to battle against the environment as well as other players to ensure they maintain control of their lands.
