My theory to explain the Firelink Shrines: They are the same shrine in 3
different points in time. The shrine you regulary go to is the earliest
shrine. Teleporting to an area sends you to that area later in time.
The dark fire,link shrine is not in the abyss. Lothric Castle has been
built over it in order to hide it.That is why it is dark. It is not in
the Abyss, it is not after the fire has faded, it is under an entire castle. Why? Because you placed the
head of Lothric in the Earliest version of Firelink Shrine. It was found
later and taken to mean someone would eventually kill the prince and
take his head to the shrine. Firelink was hidden as a result. The
Firelink shrine at the end of the game is the farthest in the timeline.
The remains of the Kingdom of Lothric are crumbled all around Firelink
Shrine and the first flame has surfaced from underneath the ground. The
only hole I can think of in this theory is Champion Gundyr. But its only
a problem if you assume Champion Gundyr and Inyx Gundry are the same
being. That being said, you don't get a boss souls from the iudex gundyr bossfight. Only the Champion Gunyr bossfight gives you a soul. If we take this to mean he did not die in the first fight, then it explains his fight in the Untended Graves. You saved him from the dark growth on his back and he returns to full strength later on.

Just a theory."

Hát az biztos hogy lehet szépen ötletelni, hogy mi a helyzet :)
