Elder P had four other siblings. Three older brothers and a sister. No wife. No kids. His father still acted like a matriarch who has retired and had a firm grip on his children hiding in the dark.
Elder P was the youngest out of all Elders. His father retired a few hundred years before Min became the new Ghost King. All of his siblings were dissatisfied with their youngest topping them and becoming the Elder.
However, they didn't voice any oppositions. That was before a new Ghost King appeared and being an Elder had more meaning and usefulness. They all now tried to snatch the Elder position from Elder P.
It has been ten years now that Elder P was able to push back his siblings and protected his position as the leader of his family. In a sense, Elder P was a sad being.
