Mind controlled Loki on Asgard post-Avengers

[ilostmynuts]

I'm looking for a fic where Thor brings Loki back after Avengers and his family puts him in an enchanted room where he can't hurt himself that once was used to hold Odin's mother. Loki has been brainwashed completely and keeps praising Thanos. All his childhood injuries have been erased and his body is pristine.

I know it was on Ao3, but I'm having trouble tracking it down.
