Human sacrifice! Dogs and cats living together! Mass hysteria! Depending on who you ask they may be dead already though.
Also they don't actually matter to sum like orcs hoo wordship a daedra anyway.
Don't kill Nocturnal and I don't care anyway
M'aiq, the reincarnation of Anu (BTW this is a JOKE if you haven't realised) would probably ressurect them.
They can't really be "killed". If either Aedra or Daedra dies in Nirn, they will just return to Oblivion(in case of Daedra) or to it's plane/planet within Mundus(in case of Aedra).
apparently if everyone ceases worship of one of the main aedra (the gods) the god themselves die. thats why the thalmor want worship of talos to stop, because then he would stop existing
You have to go through a lot of deep lore but the Aedra are all Technicaly dead they gave their lives to create mundus during the dawn era they only exist through a concept called mythopoeia which basicaly takes a part of a already dead aedra and shapes them into what the mortals belive them as thats why many religions in Nirn have parallels to one another this is also how they manifest themselves. The only one exempt from this is Talos who is a god through CHIM who walked 5 of the six ways and achived apothesis and mantled Lorkhan he is made up of 3 people Wulfharth, Hijati, and the Underking this is why Talos apears in C0DA he is not affected by the concept of mythopoeia using CHIM he asserted his existance in Mundus he is one of the things in the current Kalpa cycle that is unique. and probably does not want the cycle to reset so the Thalmor ultimately fail in killing Talos.Â
To summarize what TheBlackOmen seems to be saying, the Aedra gave up everything that made them physical, "real", and distinct beings when they created Mundus. Now, they only exist as the personifications of concepts, without physical form. For that reason, they can't really be said to die. At the same time, that would mean that 139.218.65.96 is half right. If no one worships an Aedra anymore, then would no longer be capable of manifesting themselves or interacting with Nirn, but so long as their concept still exists in some form, so will they, and if someone begins to devote themselves to that concept again, they'll reappear. For example, if suddenly commerce just stopped being a thing, just everybody stopped all manner of trading and just did everything for themselves and never exchanged anything, Zenithar would be rendered powerless. But as soon as someone got the idea in their head to start exchanging what they have but don't want for what they want but don't have, Zenithar would be back.
Talos, essentially, transcended mortality by way being just that awesome. He is different from the others in that rather than descending to Aedra from Original Spirit, he ascended from being a mortal.
