Harry Potter and the Immortal's Playground (смешанная)

It starts slowly, the steady disconnect between who he is and who he should be. The man in the mirror becomes a stranger to him; he looks into the glass and wonders how everything became so distorted and backward and...wrong. He notices in bursts: when Teddy grows taller than him, when he’s kissing Ginny on her lips and looking at the subtle smile lines she’s starting to develop around her plush mouth. She’s got the cutest crinkles by her eyes.
His face is smooth as it was when he was seventeen. Which was 18 years ago. He hasn’t aged a day.

Living forever isn't all it's cracked up to be. Harry Potter learns the meaning of immortality when everyone he loves dies again and again after becoming the master of death. After millennia of love lost, Death sends him to "Elsewhere" in order to give his master something new and different.
Harry emerges from ash in New Asgard. What's a man like Thor to do but offer the traveler a home?
