Miirym

Miirym is an ancient gold dragon, currently residing in Aincrad, though she spends most of her time in Phandalin chasing after Jasdaeruzylym.

History
At some unknown time, Miirym found her way to Candlekeep, where she stored her hoard (a massive collection of books, documents, and letters) deep under the tunnels.

At some point, Miiyrm encountered Jasdaeruzylym in the tunnels, in his elven form, Jasynn D'rulo. He was seeking the witch Baba Yaga to reverse a curse that had been placed on him that prevented him from shapeshifting back into his dragon form.

Miirym, having developed a crush on him, immediately set out to find the answer. But by the time she had, Jasynn had grown tired and left. Unsure of where to find him, she remained under the tunnels of Candlekeep, hoping for his return.

Hundreds of years later, Miiyrm encountered the party of Zero Uchiha, Annastasia Elizabeth Star Uchiha, and Rose. They were searching for the location of Aincrad, which Miirym was able to offer for them. Zero also wished for her to aid Angel Grove if he ever needed to call on her. Miirym greatly resented this idea, but agreed on the terms that she would be moved to Aincrad to gain eternal un-aging under Kalru's demigod presence, as well as finding Jasdaeruzylym for her.

Zero kept his end of the bargain, even managing to assist in getting Jasynn to agree to try a relationship with Miirym.

Personality
Miirym has a monotone voice, often seeming apathetic about nearly every topic. She seems to prefer dry, sarcastic humor. Miirym has little-to-no interest in her dragon form. She instead prefers to remain human and read books in solitude, if she's not chasing after Jasynn.
