Thousands of years ago he was an aging human alchemist, experimenting with ways to achieve agelessness for himself and his only grandson, Sorin. When famine was sweeping the land, the demon Shilgengar convinced Edgar to start experiments with blood. Markov and his sons trapped the angel Marycz in his laboratory and exsanguinated her, preparing a decoction from her blood and created a ritual which caused his subjects to feed on the blood of other beings. It provided sustenance to those few, but the demand for blood also culled the overall population, reducing the number of hungry mouths to feed. However, when he finally turned his grandson the trauma of the transformation caused Sorin's planeswalker spark to ignite. Sorin soon left the plane and his grandfather.
At some point during the day-night cycle imbalance caused by Emrakul, Sorin entered Edgar's crypt only to find it empty.
