Ever since Hermes' reveal in chapter 18, He has revealed that the old man is not the Clement that abandoned the hotel decades ago. Clement supposedly died prior to the events of the Prologue. The letter you receive a few chapters back also is hinted to be sent by the same old man that was assumed by the Player and Asterion to be "Clement." However in chapter 18, Hermes reveals that the one who sent the letter and the original holder of the deed is one of the Olympians out of the twelve that voted in Asterion's favor. When finding mementos in the valley we are able the find the transcripts for 8 of the Olympians that attended the trial, that being: Hades, Hestia, Hermes, Dionysus, Poseidon, and Hera according to her transcript. Out of those 6 Olympians we can rule out Hera and Hestia because it is a old man. We can also rule out Hermes and Hades since Hermes is already present as being young and Hades is still ruling Hades. That leaves two Olympians left being, Dionysus and Poseidon. Now back to the letter that was sent to the hotel and delivered by Hermes. The letter you receive is an apology letter with the initial signed as P; therefore, the old man that gives us the deed, and the original master as once a master dies it reverts to his next of kin or a still surviving master, is in fact the Olympian god of the sea, Poseidon. I wanted to discuss about this as soon as finished the build a second time and gather thoughts on how Poseidon still cares for a descendant of his prized bull.
