Harry never imagined that he'd find himself cooperating with Voldemort, but that was before the two of them were locked in a room without their magic and ordered to have sex by a very angry mirror. (Or: a crack-y f*ck-or-die fic that grew feelings. Takes place early in Deathly Hallows.)

All was not well. Voldemort survived the final battle and was imprisoned in Azkaban, bound with a magic-restraining collar. Meanwhile, Harry's magic started growing unstable after the loss of the Horcrux. Six months later, Harry visits his nemesis, intending to get the Horcrux back, but he gets more than he bargained for-namely the former Dark Lord magically bound as his slave.

Lily tells James Potter a secret that changes everything, James devotes himself to making things right with Severus, and a Wizard's Oath brings the three of them closer than they ever expected. (Eventual James/Sev/Lily OT3, but the story will mainly focus on James/Sev for a while.)

With a little help, Harry presses the boundaries of time travel to comfort his younger self in his darkest moments and give himself the friend he never had. There are rules though-Harry can't change the past, and his younger self isn't allowed to remember Harry outside of their interactions. As years pass, their relationship takes a turn Harry never expected. (HARRYCEST, TOMARRY)
