AU where Peter Lukas is not avatar of the Lonely but just a very introverted sea captain. He also happens to share the same last name as family of Lonely avatars but there’s no traceable connection.

However due to his lifestyle and last name Jonah assumes he serves to Forsaken and is member of Lukas family so he deems him as a great marital match for himself. They possibly meet somewhere by accident or through Salesa or something like that.

Peter is charmed by him and agrees to marry him. He is making quite a lot of money so Jonah cannot get any suspicions in that regard. Peter also has a vague idea there is something supernatural going on - Oh it appears his husband changed bodies while he was gone. Oh well, the good news is he’s not dead - but he decides to just accept it.

It goes for a while like this and Jonah only realises his error when he wants to make a bet about marking his Archivist by Lonely and Peter is finally forced to admit he had all those years no idea what he was talking about but he was just too awkward to ask…
