After capturing the Ring Master, you decide to take a little time out at the hotel. Unfortunately a murder happens to someone who might have deserved it. Maurice was a dick and was murdered by the werewolf Loopmottin. It was sorted in the most soap opera fashion.
Elly was given a vision by the Raven Queen about a clue about the Synergy group and the god they are creating. The box was signed by the initials TZH. By unlocking the malachite box with help from Loopmottin and the Black Spider, the group was transported to the Ethereal Plane and found Paige - a paper tiefling - and the lost temple of Lethe - the god being recreated by the Synergy Group.
Lethe is a god tasked with ending the world but decided to sacrifice herself instead of that. The priest advised all physical parts of Lethe have been recovered and only her mind remains.
You were returned to our world with this new knowledge, ready to kick Viktor's ass.
