   Summary

   Stephen stood at the edge of a dying reality, his breath shallow, his body trembling—not from fear, but from the unbearable weight of knowing.

   He had failed.

   Not just as a sorcerer. Not just as the Sorcerer Supreme.

   He had failed the universe itself.

   He had chosen him.

   Tony.
