Justice League Dark Teaser Update

During the Resurgence Mega Capsule Livestream, either on purpose or by mistake, an image of a new location was leaked on stream! Now what or where could this area be? An entrance to the House of Mysteries? Limbo Town? Zerox, where Mordru’s from? Another magical dimension? Also is this the new open world area or another instance? We will likely find answers to that question in the coming weeks, so stay tuned for further updates!
