Arkay - Lorkhan introduced limits, and by definition, death into Mundus. But might as well throw this chump in. Everything about him is unoriginal in terms of every other deity. Cycles? Azura. Seasons? Kyne. Life and Death? Lorkhan.
Zenithar - Your mundane Magnus and nicer version of Clavicus Vile.
Stendar - Another watered down Lorkhan with some Auriel vibes tossed in. Stuhn is more interesting.
Mara - Oh look, another love goddess. And the least arousing type of love to boot. Kynareth is described as a mother, and Dibella is a glorified whore. Why do we need a third goddess who's gettup is chastity and platonic love?
Hjalti spoke with King Wulfharth's tongue, and the very Greybeards announced Ysmir had come again. The Nords rallied to their King to take back the Ruby Throne in the name of Man.
This is Lorkhan's realm. We are his people. Congratulate yourself, petty elf, as your mystics sit for long ages wallowing in self-pity. With but out lord's heart, your empires have crumbled.
I kind of like all of them to be honest... I don't think there is a god that doesn't interest me in some shape or form, and even if I don't like their domains (Molag Bal, Namira, etc.) the actual Deities are interesting enough in their lore that I can enjoy them as fictional characters.
Backstabbed his way on to the throne, wiped out entire bloodlines to keep himself there, conquered Tamriel in some Manifest Destiny shit, pushed his baby-mamma down the stairs, and when the last people left that would stand against him were the Altmer he tried to wipe them and their homeland from the face of Nirn.
The details of the conquest of Summerset are sketchy
I ask you in all seriousness, what was Tamriel like before the Tiber Wars and the Third Era? Despite what happened, did Tiber make it a better place to live? Is there something about the Interregnum which made it a more desirable period to live in than the era of peace and stability the Red Jewel of Conquest brought?
