So Jon with accelerated healing abilities, Jon who can’t die unless his eyes are destroyed. The rest of his body, unimportant, his heart doesn’t even beat. Anything done to it just heals, after all the Archivist can’t Archive if it’s too injured.

Give me Jon realizing this, trying to die, not knowing it’s his eyes. Throwing himself at anything that will hurt him, the pain always there but the marks fade. Give me Jon getting addicted to that feeling.

Give me Elias unable to resist returning to his Archivist. Jon begging to be hurt, Elias obliges of course, conditioning Jon to mix pain and sex. Anything Elias does, as long as Jon’s eyes are fine healing. Elias fucking him while his stomach is carved open, putting out cigarettes on his chest, the little burns healing in a matter of minutes, but Jon feeling every second. Pushing further and further as the pain mounts until Jon passes out coming on Elias’s dick as he feels the knife pressing into his chest until Elias can grip his unbeating heart in his hand.

Jon coming to covered in blood and cum, both leaking out of him as his body heals enough for semi-coherent thought. Elias deciding that he can postpone his apocalypse a bit while he tries out the limits of his new toy.
