Yellow everyone. So, Lorkhan is dead. His flesh, Secunda and Masser, is rotting in the sky and will eventually disappear. Does that mean that Lorkhan exists no more? Is he ever going to return? Where do gods go when/if they die? And what happened to Magnus? A part of him is still on the world, what about the other part? Is it in Aetherius?
Lorkhan exists in half-death. (See http://www.imperial-library.info/obscure_text/aldudagga.shtml#6). It is unknown whether he will return, although it has been hinted at that he will, in fact, return one day. It is unknown where gods go after they die. The Aedra that have died turned into the Earthbones, otherwise known as "the laws of nature". Magnus left Mundus before it was completed to avoid being trapped here with the rest of the Aedra. The hole that he tore in Oblivion to get back to Aetherius is the sun, so no part of Magnus is still on the world.
Can someone elaborate on Secunda and Masser? I too thought that they were to do Lorkhan's body, but luagar slapped me down and told me that they weren't.
Lorkhan is and is not. I haven't reached a level of mental madness like some lorelords here. They'll help you better than I can, I want to know the moon question though.
Secunda and Masser are the two moons above NIRN. They are said to be the body of Lorkhan, torn in half when his divine center (aka Heart) was removed and fell to earth, creating Red Mountain. There are craters in the moons because they are decaying. That is my understanding of the subject, at least.
