In which you are the most powerful member of Ainz Ooal Gown and essentially YGGDRASIL, have abandonment issues, and are the one left behind at Nazarick during the game's shutdown instead of Momonga.
You thought that you were already possessive before, but being an actual dragon that lives to hoard and protect everything that it deems as yours made you realize that for dragonkin, being possessive is what made you who you are. To love and care for something is one of the greatest gifts in the world, but to protect them is the greatest honor.
The rest of the world can burn for all you cared, but if they touched even a single hair on anyone you deemed as yours...there will be hell to pay.
i like it this is a new take on this type of fanfic, i dont see any good OC fanfics that are more than 5 chapters. and if i do its more about momonga and not about the OC, so i hope you dont drop this half way or if you do at least make a ending even if you have to make a 100 year timeskip as the ending.
