The arcanist Karsus, tried to wrest the mantle of divinity from Mystryl using the spell Karsus's avatar. Immediately after he cast the spell, his body swelled with the sudden influx of godly power, and his mind filled with unimaginable knowledge. He instantly realized the horrible mistake he had made. Mystryl lost her ability to keep the Weave intact, and the inundation of magic surged and fluctuated, with the effects of all things magical doubling for a short time. To save the weave, Mystryl sacrificed herself and, in the process, broke contact with Karsus. This caused all magic to briefly cease functioning. The archmage Karsus died when the link to Mystryl was cut and his body was petrified. In the last moments of life, his stony eyes, still shimmering with the last glint of godly omniscience, caught a glimpse of the cities of Netheril smashing to the ground, killing all. His heart broke—greed for the power of the deities themselves had caused the destruction of his home, his family, his friends, and his people.
