Doctor Strange Vol. 3 Blood in the Aether (comics)

In the aftermath of THE LAST DAYS OF MAGIC, journey back to the first days of Doctor Strange! How did Stephen Strange become the Sorcerer Supreme — and how has he lost it all? In the present, Strange is on the brink of death, his magic nearly depleted. Sensing the Master of the Mystic Arts is at his weakest, his greatest foes will return from the shadows, ready to strike — starting with one of his oldest rivals, Baron Mordo! But as a parade of bad guys line up to take their shot, one of Strange's newest enemies may be the deadliest of all. During ORIGINAL SIN, one of the slain Watcher's eyes fell into the hands of the Orb — and with that immense power, he has set his sights on Doctor Strange!
