So, where to begin with. In Oblivion we have a Quest where a man needs an Artifact to open portals between planes, the Quest is separated in two Quests, being the "Blood of the Daera" and "Blood of the Divines". On this quest we need an item with the blood and energy of a Daedra and Divine being to open up the portal between planes. We use the Armor of Talos as the Divine item, and I started to think: "Maybe the portal is oppened between planes that are rulled by Daedric Princes. Where would Mehrunes Daegon get the Blood of a Divine in first place? I think both items belong to Daedras, one sacrificing the energy for the portal to be oppened, and the other being the way point to the plane that this Daedra resides. So this makes Talos a Daedra that Resides in Nirn, so the portal would open on Cyrodill." This makes even more sense by looking how the elves hate on Talos, as they hate the Daedra and Lorkhan himself. Talos was an "agent" who cause change on Tamriel, every time he faced a Challenge during the conquest of Tamriel, he would pull something from his pocket to bend the "universe" in order for him to succeed. He cause much change on Tamriel in order to Rule Supreme, and after he died, he was worshiped as a god, just like cultists do to other Daedra, but Talos made the empire, so people won't see him as a treat. Another point is that not all Daedra are Evil, some are even good but rather harsh. Take a look on Meridia for instance. Jyggalag was a Daedra who was balance itself. Talos maybe was a Daedra who was justice, he was a kind emperor yet he punished many, killed many and conquered other by force.
Tell me what you think about this teory, and please don't go around insulting each other because of Stormcloaks and Imperials. I'll make another Topic about the Civil War and my Teory later.
