Yeah, perhaps an event will happen that implies that you have joined/mantled/ascended to the divines and we will only find out in an out of game source or in TES VI.

That is what I'm hoping for. But with subtle hints within the dlc (a book perhaps) reminding us that it can be done by walking in a god's footsteps. And you do just that.

When Herma Mora murdered Storn, he scared me. The way Herma Mora just did that was frightening. His voice as well. My lord that voice. It scared the hell out of me. And then Miraak? Him killing Miraak? That shows that he is a powerful heartless daedric prince. I fear him.

HM obviously has His limitations. Just look how long it took Him to learn the secrets of the Skaal -- or how He went about doing it. Sure, He may be immensely powerful in His own realm (though Miraak was already on the verge of death), but He's just like every other Daedric Prince outside it.

A Daedric Prince cannot be killed (for plenty of reasons, or perhaps none), but they can be defeated. The Tribunal were known to have gone toe-to-toe with a few of the Daedric Princes, and come out on top. And then you have Martin (Akatosh) beating Mehrunes Dagon, the Daedric Lord of Destruction. So it'd be entirely possible for someone to defeat HM at His own game.. but it'd have to be someone like Sotha Sil, a Telvanni master wizard, the Augur, or one of the Psijics.

What I'm going to say here is based on what I remember from Bloodmoon (and my own opinion, of course) and I accept that Dragonborn may have invalidated these ideas since:

The All-Maker is responsible for the creation of the whole natural world. The Skaal don't have stories about Akatosh. The All-Maker is as much Akatosh as he is the other seven divines.
I can't see what the Greedy Man, that is, the Skaal's Greedy Man, has to do with Lorkhan. From his actions in The Story of Aevar Stone-Singer, Peryite would be as apt. The All-Maker appears to be a catch all benevolent creator and the Adversary appears to be a catch all, well, adversary and destroyer. I think the daedra in general could be associated with him, with individual demonic minions or aspects including Hircine and Hermaeus Mora.
I concede that the story suggests that he could have been a man once, so the Greedy Man could have been a Shezzarine who brought Solstheim to its knees. Although sapping the forces of nature from an island doesn't sound like Shezzarine behaviour to me.
Thartaag sounds like Alduin though.

I suspect that the Greedy Man was Miraak.

He was corrupting the stones this time around. The Greedy Man is also said to live in a "crooked house," and he was corrupted by the "Adversary." However, the Adversary sounds more like Padomay than Hermaeus Mora.

I would completely follow your line of thinking, except the Aldudaggas describe Lorkhan as the Greedy Man as imply that Akatosh (Aka-Tusk) is the All-Maker.

Idk I loved it, gave me a real feeling that hermy cared about what happened and his angry voice surprised me.

Just because the Skall believe it, doesnt mean its true.

There's a reason the Skaal have secret magic and the ritual stones actually work. They're not wrong.. they just have their own perspective on the creation of the world.

So...is Giratina is the combined form of Palkia and Dialga?

My head always hurts when I try to make heads or tails of this stuff.

But as I understand it, just as the difference in opinion between man and elf brought us both Akatosh and Auri-El, who are both very different gods yet the same, mortal belief can change Talos the same way as he's an Aedra. So if a large enough group of people believe King Wulfharth wasn't involved in the Mantling of Talos, then that is true regardless of what really happened. But if at the same time a large enough group of people believe he was involved, then that is also true regardless of what really happened.

I hate it when dragons break. Up becomes down, yet it was always down, but down stays down leaving us with no up, but we've always had an up so up it stays. Hard drugs were being passed around Bethesda when this became a good idea. HARD drugs.

I think Talos reached CHIM, he's not affected by mortal belief in the same way Aka is.

Is that what that book means? I didn't quite understand it... "Where Were You When The Dragons Broke?"

I have no idea what you are takling about.

You don't.

The Daedra are Immortal and cannot be truly killed. Even the Daedra Princes reform after a bit.

Have you tried? How do you know? They could create a soul gem powerful enough to do the job. Other Daedra can be trapped so why not a prince?

Because /insert everything we know about lore here/
