When looking at the remaining days, it seems that the deadline of the investigation corresponds to BG3 launch D8.
Does it? I thought it was meant to run up to the PFH.
Though I'm a bit worried about today's update. We were given a tenday to identify the Master on 24 Kythorn, and it is now 4 Flamerule. I'm not really up on the calendar of Faerun, but isn't that 10 days ?
According to the timeline (below the map with the white bullet points) we should only be half-way during PFH. And you are right, I had forgotten this, something related to the Master might very well occur shortly. Suspense !
