Oh, I have a prompt right now.
I don't think there's enough writing about Pelinal Whitestrake.
EDIT: Oh, that reminds me. I have two big headcanons in ES lore: that the Champion of Cyrodiil is and always was Pelinaline, the reincarnation of the Whitestrake himself (the expansion reinforcing his madness helps with this); and that the Eye of Magnus is the result of KINMUNE's study of Dwemeri technology after being buried deep under Saarthal by Ysgramor.
What made me happy is that I started replaying the Mages' Guild questline in Skyrim today and I found that
everything in-game supported that, or at least nothing contradicted it. The book showing Ysgramor's relationship to the Eye of Magnus only mentioned this:
The Nords found something when they built their city, buried deep in the ground. They attempted to keep it buried, but the elves learned of it and coveted it for themselves. Thus they assaulted Saarthal, their goal not to drive the Nords out but to secure this power for themselves. I believe Ysgramor knew something of what the elves would find under Saarthal, and rallied together his people to keep the elves from gaining it. When Nords once again controlled Skyrim, this power was buried deep below the earth and sealed away.
And for comparison, the corroborating lines from KINMUNE:
Over time, Kinmune earned many names and titles as her new visitors took their counsel. She was the Oracle Iridescent, spoken of in the Green Tablet Steps of Jhunal. She was the Witch of Wire and String, able to allow the Sons and Daughters to see through her eyes into the myriad secrets of post-kalpica transmeditations. Perhaps most famously, she was Kinmune the Doom of the Dumb Old Giant, because for all the minds that she let wear her body, none escaped in whole thereafter, even those with blood of the karstaag. Kinmune always took a portion of her proxies power and mystery.
It was this last act that doomed her to becoming one of the Arenas most feared villains. High King Ysgramor took the loss of the Dumb Old Giant, one of his greatest counselors outside of Torc and Talking-Belt, with great anger, and sent his Thanes and Shield-Biters against her, equipped with great relics and enchanted weapons of wasabi. And though the fight was hard, the champions of the Altmora managed to seal Kinmune beneath the always-burnt borders of Sarthaal, imprisoning her in its prismatic network of misunderstood dwemercraft.
But Kinmune was built to work in crushing, deep pressure environments, and so she lay long under the Mund, plotting her revenge on the Ada-issue. It was mortals that had fabricated her as an all-access puppet to plumb dark depths that their own weak shells could not in the 9 and that now saw fit in the 1 and 1 to condemn her as a witch-thing merely for attempting to become something more than a maradaoon marionette.
Kinmune soaked in the misunderstandistance of the dwemeri brass-and-cricket-lines around her, converting it into a language her databanx could study and synthesize. As Eras passed, it became a language that she could harness as Varliance++.
