I'm not sure specifically as there could be many novels with such a title. It might be about a mafia king who falls in love for the first time, perhaps facing conflicts between his mafia world and his new - found love.
In most cases for this kind of novel, the mafia king is the central male character. He is usually portrayed as powerful, dominant, and a bit of a mystery. His first love, let's say a young woman, could be from a different background, maybe she's a simple girl who works in a normal job or is a student. There could also be other characters like the king's right - hand man in the mafia who might have an opinion on his relationship, or the girl's friends who are worried about her getting involved with a dangerous mafia figure.
Well, disputes over property rights are a big reason. This could be due to unclear boundaries, as in the case where two neighbors think they own a certain piece of land and one tries to get a writ of posession to claim it all. Another reason is when there are competing claims from different parties who all think they should have the property. For instance, in a probate case where there are multiple heirs and one tries to get exclusive use of the property through a writ of posession. And sometimes, developers may seek a writ of posession to start construction on a property where there are hold - outs, like tenants who don't want to leave.
In the realm of fanfic, 'abcd posession fanfic' is rather ambiguous. It could be that 'abcd' are just code names for something within a particular fandom. 'Posession' is a broad term that can cover a lot of ground in storytelling. It could be a dark fanfic where characters are forcibly taken over by an external entity, or it could be a more metaphorical possession, like a character being consumed by an idea or emotion. Since we don't know the specific fandom or the intention of the creator, it's difficult to give a more comprehensive understanding.
You could try searching on popular fanfic platforms like Archive of Our Own (AO3). Just type in 'abcd posession fanfic' in the search bar and see if any relevant stories pop up.
Sure. One writ of posession story is about a family who had been renting a house for years. The landlord decided to sell the property. When the new owner took over, they filed for a writ of posession to legally evict the tenants. The tenants were shocked as they thought they could stay until the lease was up. It led to a long legal battle over the proper notice and the rights of the tenants.
They also show the hierarchical structure. The bosses are at the top, making decisions, and the lower - level members have to follow orders without question. In many mafia novels, there are descriptions of how power is maintained and transferred within the organization. Like in 'Gomorrah', we see how new leaders emerge and the old ones are either overthrown or die in the process. This shows the cut - throat nature of the mafia world.
There's no way to know exactly who the two kings are without more context. They could be fictional characters created for the story, or they could be based on historical kings from different regions.
