Too Far Gone
It doesn't matter if you only have one way to die when you have no way to win. That's what we call a no limits fallacy anyway, typically banned in these threads to prevent the constant back and forth of no limit spear vs no limit shield type shit.
Dragons in Elder Scrolls are also only killed by Dragonborn. Their soul remains, which is how Alduin brought them back. A no limits thing, again, but I'm hoping this helps me make the point not to underestimate the races of Tamriel.
Anyway, Daedra are some of the most powerful godlike beings in existence, capable of doing just about anything. And the creation story in ES goes that, when Lorkhan tricked the other gods, their divinity was being drained to create the realm of Mundus. When some gods caught on, they left the realm and went back to Aetherius, creating the stars, holes into Aetherius through which the Magicka flows into Nirn. Magnus was the first to leave, retaining the most of his power, which is why the hole he left is the largest, the sun.
There are also scores of things in ES that we don't know anything about. The vast majority of the continent of Akavir, for example. It's apparently home to the Tsaeci snake people, who may or may not be immortal like the dragons, an entire nation of tiger people who's leader found a way to turn himself into a dragon, a nation of "snow demons," hundreds of islands populated by monkey people, the old continents of Aldermis and Atmora, as well as possibly thousands of smaller and larger islands between all of these continents.
Like I said. I don't know Dragon Age, but if that one dragon from a thread with Quanchi was one of their most powerful living beings, the ES verse has the mortal battlefield claimed already, and I'm betting Magnus won't be highly bothered by these Old gods.
