Hi, so I need help looking for a specific fic. I remember it was a godstiel fic where Castiel wakes up with amnesia of his time as Godstiel. He finds Dean who he has turned as his puppet consort and finds out that as Godstiel, he had ripped shards of Dean's soul and hid them all over the world (and the moon). I remember him restoring Dean and finds out that there is a big soul shard missing and it turns out to be in himself and what cleaned out the Purgatory souls. I remember that there was art that goes along with it.

Certain details that might help:
Castiel took Dean to the Maldives and made it their homebase
There was an art piece of Castiel wearing armor like medieval knight armor.
