The Mindscape

The massive network of sentient minds connected through the Golem of the Pit by Dagoruk in an effort to stave off the end of the world. Through the Mindscape, the people of Loredas were able to continue to exist while Ephemera took the rest of the world.
The Mindscape took several forms of a collective dream, shaped by its creator Dagoruk, but also the dreamers themselves. First it was a cyberpunk city called Haven embroiled in war that took the lives of many, but upon entry by Maddox and other members of Athrun's cult, it morphed into a much smaller, denser city known as Waterdeep where several dreamers clashed with him and his henchman to save the dream and allow everyone to awake safely.
