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. Either way, Velsaert was labelled the "Dragon Sage".

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" on 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."
 * Gaulauntyr: "...one long series of hurried escapes and misdirections" on his interactions with fellow dragons.
 * Jalanvaloss: "shown no signs of desiring the company of other wyrms, nor of dwelling in solitude or defending any sort of territory."
 * Klauth: "a grim, nasty, awe-strikingly huge red great wyrm who has slain many rivals in a career spent on the attack, aggressively mauling everyone within reach."
 * Lhammaruntosz: Velsaert felt that Lhammaruntosz's understanding of humans was key to her character and that her Scaly Eye fleet served as her surrogate family, as she distrusted her fellow dragons.
 * Mornauguth: "a series of skirmishes between a reckless, ambitious interloper who cares for treasure only as a means to further her schemes, and wyrms defending hoard and domain in the traditional sense." on his interactions with fellow dragons. Velsaert mistakenly refuted claims Mornauguth hired adventurers to help her.
 * Nurvureem: "That deadliest of dragons—the sort who evades battle and all the other outward show of draconic life, to lie low when other wyrms roam or seek to do battle... only to rise up when unexpected and strike out of the shadows like a merciless snake."
 * Nymmurh: Velsaert felt Nymmurh saw fellow dragons the same as he saw humans: entertaining but potentially dangerous, and wise to learn as much as one can about.

Relationships
Curiously, Velsaert was reportedly advised on draconic nature and affairs by the bronze dragon Nymmurh.

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.
