The Living Pentagram
The existence of a plot to create a living pentagram was first discovered by Jim Fritz while hacking into the LawTech computer system. The information he found suggested that EVIL Corp. were attempting this in order to summon and trap death, though the precise purpose of this remained unclear.
It was later found that the ritual to create the living pentagram was taking place in the cellars of a number of hotels within Bludhaven. In order to stop this the gang split into pairs, with each pair taking one hotel in order to defeat the cultists within. While this was entirely successful, doing so resulted in a disruption to the timeline and each pair waking up on 1st December two years later having lived an entirely different timeline, but with vived memories of what had happened previously.
