In case the Lore-related dialogue is a bit buggy/confusing, here is the lore involved in the mod:

WARNING: DO NOT CONTINUE IF YOU HAVE SOME SORT OF PERSONAL LORE

The Elder Scrolls Universe is a dream. A godhead is dreaming up the universe in an endless cycle, perpetuated by cycles called kalpas. These kalpas make the dream remain stable, and they're begun and ended by none other than Alduin. His "eating of the world" is more akin to a resetting of the Elder Scrolls Universe. However, in the modern kalpa, his duties have been forestalled. Twice. Naturally, this could possibly have consequences. This mod adds in the consequences by putting in "corruptions" into the Godhead's dream in the form of these Easter Eggs.

Terms to Know:

CHIM: The state achieved when an Elder Scrolls character knows the truth about the Elder Scrolls Universe and doesn't zero-sum (thinking and truly believing he/she doesn't exist, so that person dissapears in a puff of their own logic) out of intense self-love. They gain powers similar to that of the player (not the Player Character, the actual Player. Ex: Access to a Creation / Construction Kit like utility, observing glitches in the game itself, etc.). Two people are suspected of having achieved CHIM: Vivec and Tiber Septim.
Godhead: The being that is dreaming up the Elder Scrolls Universe. Many, however, speculate that the Godhead is the video game itself, therefore all who have CHIM know they're in a video game.

Note that the Lore of The Elder Scrolls Universe is on-purposely left to speculation by the developers, so all interpretations vary based on the person interpreting the data presented. Please see me for any questions, concerns, or crises.
