Summary
Tony Stark, patchwork immortal extraordinaire, is tired off 'people' and 'adventures' and crap like that. He's gotten mellow, really, but that's what time does to you after a while. Now he just wants some peace, what he get's for a couple of centuries, until (unknowingly) he finds Loki's student being hunted in the middle of his stupid forest in Alfheim. Frostiron, 700y post-canon.
