The magi know about the Keepers and the Scarabae, and they have clues to where the three remaining keys are needed to open up the lower levels of their covenant. The theme has changed from "what do we have?" to "what shall we do with it?". The new alliance with the last members of House Diedne could be a powerful boost to the fortunes of the covenant, or it could bring about its downfall. With the servants of the Scarabae sniffing ever closer, the magi may not have as much time as they would like.
Notes from this last part of the campaign were never written up (I'm not entirely sure why).
The lower levels of the covenant was finally opened, revealing a great city where fey creatures lived and kept the rituals of confinement going for a very powerful old god. The Scarabae and Keepers were two opposing factions from this time, and were seeking his resting place for their own reasons. In the end, the magi break the ritual, and Mythic Europe is reshaped as the old gods awaken.
