From itch.io:
You are the Last Magus, out of your tower, witnessing the world you once knew crumble, fall to pieces...
The shadows grow long, and in these final days of this Age of Magic, you sense a familiar presence beckoning you from the shadows, calling you to rest.
It is Death. It is patient.
Your work is not yet done. This is the world that you loved for all your long life, filled with marvelous places and the most precious of people. Uncertainty reigns. You can bring order to the world, even as your magic dwindles. This chaos strikes like birthing pains, so you must deliver the world into another Age, one where you will be absent and they will live on, remembering.
In The Last Magus you take on the role of a powerful sorcerer of your own creation, with your own past and motivations. Travel through the provinces of the Empire, and in each province uncover a crisis waiting for your intervention. Control the weather, summon demons, create elaborate illusions, or boil the blood in your enemies' veins. Restore peace using sorcery, limited only by your imagination, or bring order with more worldly, diplomatic means.
And yet your time is ending, Magus. Another force stalks these roads. It is Death, who you will meet in many guises, and with whom you will bargain for time. So little time...
