Velsaertirden

Velsaert was a loremaster and sage based in Baldur's Gate in the mid-to-late 14 century and an expert on the dragons of the Sword Coast. It certainly helped that he secretly was one himself: a very old steel dragon named Velsaertirden living in disguise as a human.

Activities
As Velsaert, he had written of, and indeed commented on, many of the more well-known wyrms of the North, including:
 * Eldenser: "A parade of friendly hidings—but ready deadliness." with regard to his interactions with fellow dragons.
 * Felgolos: "An eternal wide-eyed blunderer, ignorant of draconic etiquette and ways, but more learned in the doings of humans and treants and hedgehogs than the wisest sage alive."
 * Galadaeros: ""Polite but brief and casual encounters; he offers no menace but in turn ignores it when offered to him—and then removes himself while the other wyrm is still lost in puzzlement."

History
In the late 1360s and early 1370s DR, Velsaert was swiftly gaining a reputation as an expert on the lives and times of the dragons of the Sword Coast.
