Ars Magica Dies Irae - 5th Edition (Apocalypse) Sourcebook
[Pen & Paper]

In Mythic Europe, some wizards serve the terrible powers that ruled the world at the dawn of time, and plot to grant them mastery once more. Others would take everyone to a glorious new existence, careless of whether they want to go. Still more have nothing but the best of intentions, but risk anything to achieve their goals. If they are not stopped, their power will twist and consume the world and all who live in it. 

*Lest All Be Lost* 

This book describes four great threats to Mythic Europe, with stories centered around both attempting to stop the disaster, and surviving the aftermath if the characters fail. These threats go far beyond a single covenant, or even a single Tribunal; all of them could lay waste to the whole of the world. When the fate of the world is truly in their hands, will your characters rise to the challenge, or let everything fall to ash?
