Fate/Tower of God - Climbing the Tower with Mordred (fanfic)

With Servant Card of [Mordred Pendragon] and with Mordred's spirit inside his Ignition Weapon [Clarent], a reader enters the Tower. The Tower. It is said that anything could be found at the top. That any wish could become a reality. No one had yet reached the top, though. After hearing about the Tower of God, Mordred's goal became to climb the Tower in order to fulfill her wish. As for the reader Orion, he is the vessel of her Heroic Spirit powers and her partner in crime that promised to make it happen. The two made a contract to climb the Tower together to reach the peak! ... It's a story that I'm casually writing on the side after being inspired. I felt I had to mention it, since there is no guarantee I'll finish it (even though I have a good idea for the entire season 1). I wonder what the response and popularity would be like. I also like the fact that the MC's powers here are quite straightforward, and it makes things easy to write.
