The Next Day.
Last night, Sam dealt with the wraith by completely extracting its soul.
However, something peculiar happened—rather than simply disappearing out of existence, the soul transformed into an orb of blue-black energy that emitted soul power, along with something else.
Sam suspected this phenomenon was likely due to one of the dormant abilities he had awakened after absorbing the wraith's excessive soul power.
He particularly believed it was related to an ability called Shadow Heart, and the other ability he awakened was known as Warrior's Rage, which also sounded powerful.
He wanted to examine them further, but he was interrupted when his mother, eldest sister, grandmother, his saintesses, and the academy staff came searching for him in the Forbidden Forest.
After everything he had gone through, he allowed himself to be vulnerable for a moment in his sister's arms.
