A video was posted in the channel.
The video contains rapid flickering between this sentence: "
EXPLORE HIS ORIGINS" and multiple images depicting AO concept art. There is also a date in it: 2018. 03. 20.
My theory is that the Lost Archives / something else related to AO's behind-the-scenes are going to be released as a documentary/book.
