Gravekind

Gravekind is Zariyah Gunn's main Strife Specibus, and is the first Kind Abstratus to be seen in Synodic Reboot.

Quintin's Grave
Zariyah's first weapon, which she had since before the comic. The grave belongs to Quintin; Zariyah's accidental allocation of it has prompted him to haunt her relentlessly, while he was still the Vengeful Spirit. It's the only thing she was able to fight it with, seemingly having the unique ability to physically interact with ghosts.

During Zariyah's entry, the Vengeful Spirit hit her with enough force to knock the grave out of her house's entry range, resulting in it being left behind on Nobriel and leaving Zariyah without a weapon. After Quintin became prototyped and regained coherence, he expressed discontent at the loss of his gravestone, resulting in Zariyah prattling Rennard to ask him if he will retrieve it while he's still on Nobriel.
