Mora could just simply be an allusion to the affinity Elves in fantasy have with nature, namely temperate forests. Strangely, the Mer (sans Telvanni Dumer and Bosmer) seem to have no better bonds with the natural world than men.

Yeah, I remember that. That's why it's called the Deadlands. It was dark and gloomy and nothing was alive. Atleast until Dagon started invading. I know a Prince's mood changes his realm. Maybe it got all hot and volcanic because he was getting an adrenaline rush while invading.

Sorry, I have not noticed that sans) Mea kalpaculpa.

It's alright, common mistake.

nope. Seif-ij Hidja thought that Morion Zenas had entered the deadlands when he found himself in a "landscape of dark twisted trees, howling spirits, and billowing mist," but, that was really Quagmire, the domain of Vaernima.

In reality, nothing in the lore contradicts Oblivion's depiction of the deadlands.
