Hela and Hel

In Siege: Loki was shown, that Hela haven´t any place to rule. But her hell must be some other realm, some mystic place so it can´t be destroyed in ragnarok. Or it was?
And if it is away, where are all souls which was in her kingdoom for all centuries?
I tought, that every other world (for christians, asgardians, etc.) is something etneral, when it is for eternity for souls of death.
And what was with all that died after third series of Thor, when they have no place to go?
Disirs are ghosts, or something like that, it is crazy, that no one, even Hela, lady of death, wouldn´t know, if they really exists, or not.

Hell in Marvel universe is just one place? Just like Earth it is realm with few areas like states govern by most powerfull demons? Where was Meggan in Cap. Britain and MI13 annual? It is the same place where goes souls of other death people, or it is something different? Mephisto is absolute ruler of this place, or there is more realms (separate one from each other).
It looks to me that editors in Marvel were fired out many years ago and every writer put in global relations what he wants. Could someone with knowledge let me know more about this stuff?

The Ragnarok finale of Thor Vol 2 wiped out everything Asgardian, including all the Nine Worlds beyond Midgard, Earth. Surtur's Muspelheim, the Frost Giants' Jotunheim, Nornheim, etc are all gone. Thor's resurrection brought back the realm of Asgard and, eventually, the inhabitants of the realms, but not all the realms themselves. Hel is gone, as is Valhalla, Hall of the Honored Dead, where mortal warriors were gathered for the inevitable coming of Ragnarok. Ragnarok has come and gone, so there is no more need for Valhalla.

Those realms of Elves, Giants, etc. got destroyed, too, in the Ragnarok. Withess recent issues of X-Force, with Rhane's wolf-prince.

Not all the Gods are creators. Hela is the bastard-offspring of Loki and the Giantess Angrbode.... Hardly prime stock. She isn't even a Godess as such as I recal. She's Hell's ruler, but not the Godess of Death persee.....

Odin, Thor, Balder, Freya, Njord, Aegir, Tyr, Freyr, Vidar, Hoenir... I'm not that sure about Heimdall, even....

Sif and all the others are mythological characters, but I'm not sure if the ancient Norse actually prayed to her.....

I think they were considered Aesir, but not Gods....

In Thor 610 we see, that Valhalla is still there. I must repeat myself that it is strange. They have no order in it and writers don´t realize it, or they have chaos in their plans. Or it is Hela´s place, but it is strange that no one act as if it is something new. They don´t care about dead beofre, or it was still here or is hela´s work and they simply accepted it and also accepted lost of souls died before her deal with mephisto. Marvel need some order, where are all editors?

Mostly I want to say that is strange that with so many deaths no one care about their souls in afterlife. Loki did it for herself, but if he don´t do it, nobody will do nothing with it. It doesn´t look very noble for proud asgardians and Thor especially. And before Monolith wrote that Valhalla was also destroyed. And Hela said in New Mutants that she has no job, because she has no place for death souls. It must means no hell and no Valhalla. Nobody missed it and now it is here and they just take it as a fact. I don´t know, maybe I expected some connection and explanation in story, not just some underlined story sequences for readers without proper fitting in story as a whole and also maybe some more godlike presentation of asgardian GODs.

It seems that Valhalla has become the place that the warriors just go after they die...like the common myth goes (the part about Ragnarok is typically left out of leypersons explanation of it).
