Sekiro is linked to Elden Ring......

So I’ve seen so many numerous people trying to link Sekiro world/lore to Dark Souls, but I believe it’s linked to Elden Ring instead... Think about it, the divine dragon and the dragons heritage are firmly confirmed to come from the land of the west.. However, resurrection is vastly different from the hollow curse we know from the Dark souls series. There’s also no mention of souls, or power from souls, even when defeating the divine dragon, which again comes from the west. I believe Roberto, or the Armor clad knight, is further proof of this idea.. He seeks to cure his sons illness, and brings him to Ashina in search of the rejuvenating waters.. If the son suffered the major Souls game illness, it would be the curse of un death, and seeking a path to immortality would be the LAST thing you’d see as a cure to that. Not to mention if he WAS trying to cure a curse/illness of un death he would venture to Londor or the associated lands to the legend of Undeath at the time. We ALSO have seen decaying flesh or rotting flesh in the Elden Ring trailer, which seems much more like an illness than a curse. There’s also very subtle hints to my theory as well, such as lightning being the all powerful element in Sekiro, while we see lightning sparks as a main detail in the trailer for Elden Ring. It should also be worth noting that fire isn’t highlighted in the Elden Ring trailer at all, and it’s nothing more than an element in Sekiro as well (the only exception being Shura). QWhile lightning could be associated to Gwen or dark souls there’s a very easy explanation. In Sekiro lightning ONLY comes from the sky, or is imbued into an item (sword, arrows, balls of Okami) and NEVER summoned from an individual and used on its own. Also, the only “ring” type item we find in Sekiro, is the Malcontent Ring, which is a VERY special item, while in DarkSouls rings are common enchanted or imbued items found in abundance. We also know that Elden Ring takes place in a western style world that has been ravaged by something, and the Divine Dragon is directly described as “Fleeing” from the west. The easiest connection of course, is that in the Elden Ring trailer we see very clearly a warrior attaching some sort of “prosthetic arm”, and more specifically it’s the opposite arm of Sekiro’s prosthetic arm.

This is still just an educated speculation so feel free to tell me how I’m wrong, or how you agree!
