I've been chewing on the Moth Priests longer than I care to admit. The usual line is that an Elder Scroll just overloads your eyes like some kind of magical radiation. That undersells it. My thesis is simpler and sharper: the blindness is a deliberate metaphysical cost. Unfiltered confrontation with true history exacts a physical and spiritual toll because TES cosmology prefers lived myth over raw knowledge.
Look at what actually happens on the page and in the game. In Dawnguard, Dexion Evicus is a fully trained Moth Priest who has spent his life with the Ancestor Moths. He reads the Elder Scroll for the prophecy and loses his sight for good. He treats the loss as the expected price, not an accident. The moths are meant to cushion the experience, yet the cost still lands. Contrast that with the Dragonborn reading an Elder Scroll at the Time-Wound on the Throat of the World. Same class of object, different outcome. Temporary shock, sure, but not the permanent burn. Dragon blood or Akatosh's stake in linear time seems to rewrite the terms of the deal.
What the Scrolls actually contain is the problem. They sit outside ordinary time. They hold every possibility, every Dragon Break outcome, every version of events that the cultures of Tamriel later smooth into single usable stories. "Where Were You When the Dragon Broke?" shows gods and mortals alike experiencing non-linear time as overlapping truths rather than one clean timeline. The Monomyth itself is a patchwork of culture-specific creation accounts, all left standing as valid. A Scroll forces the absolute version into a single mind. Mortals are not built for absolute. The eyes go first. That is either mercy or enforcement.
This is why the whole cosmology leans so hard into lived myth. The 36 Lessons of Vivec never hand you a clean fact sheet. They bury the metaphysics in poetry and contradiction so the reader has to live the lesson instead of merely knowing it. The Alessian Order rewrote history into a myth that could hold an Empire together. Even the Tribunal's project was about becoming the story rather than cataloging it. Raw history short-circuits that. It is like forcing a mortal to stare at the bare machinery of the Dream without the cushion of narrative. Blindness is the system saying you may look once, but you will pay, and most of you will stop after one good look.
I am labeling the next part speculation, though it follows from the sources above. The toll may protect the stability of Mundus itself. If enough people could casually read true history without cost, the linear experience of time that Akatosh maintains might fray further. Dragon Breaks already prove the fabric can tear. Blindness keeps the Scrolls rare and the knowledge expensive. It privileges the hero who lives the myth (the Dragonborn, the Nerevarine) over the pure scholar who only catalogs it.
The priests know this. They accept the dark. That acceptance is itself a form of lived myth: the blind seer who traded ordinary sight for a different kind of vision.
So which do you weight more when you think about an Elder Scroll: the physical object that burns eyes, or the infinite simultaneous histories it forces into one mind? And does the Dragonborn's relative immunity at the Time-Wound suggest that dragon blood is simply a better buffer than any moth ritual the priests can manage?
