For the last 200 years, Elias has been there, Guiding his Archivist. It's an onerous job. Jonah, In whatever form he takes, will always be Jonah. Unfalteringly curious and prone to putting himself in danger. Jon is no exception. He'll take the hateful glares and impertinent remarks as he has done so a hundred times. It's the same song and dance really, Its all a matter on time before he is Elias' once more.
And besides, Jonah always settles down once he's lost an assistant or two.
Focus on current day Jon/ Elias or even 1800's Jonah/Elias! (Hell you can even pick a reincarnation in the middle). Smut or no smut! It doesn't matter! Just please give me more creepy Elias!
PROMPT: Onesided Elias/Jon (Jonah Magnus) Reincarnation. Obsession
