It was wise of you not to come here at night, it would be just a suicide. But don't be a fool thinking it's safe now as you never know what might be hiding inside the mist. It's ephemeral transparency is just an illusion.
This city is built with the Dystopia Commercial Set presented on Thereafter event (August 17th - 27th). Quite a functional set to create a post-apocalyptic shopping event with old church ruins shaped as a stage and eight commercial booths in abandoned houses. There is also mossy looking ivy add-on for a creepier look.
