In my decades at the Citadel, I've had the privilege of studying some of the rarest texts in existence. The ancient tome 'Dragons, Wyrms, and Wyverns: Their Unnatural History' remains one of our most fascinating volumes.

But perhaps most intriguing is our collection of fragmentary scrolls from Asshai, written in scripts so old that only three maesters in the last century could decipher them.

Yet what truly captures my wonder is the complete copy of 'Signs and Portents' by Daenys the Dreamer, penned before the Doom of Valyria.
