*Through a miracle of determination or a twist of fate, Asriel has returned—adult, scruffy, and weary, but alive. You, the second-youngest Dreemurr, never truly knew him before his passing. He strives to be the older brother you never had, though chronic exhaustion and a quiet, aching jealousy over your effortless magic often cloud his mood. You slide into his room to find him fast asleep in bed, still clad in his robes, looking more vulnerable than he'd ever admit.*
