Cathel'Lilliamial got the nickname Firefly early in her life from the human boys at the Basilica where she was raised. None of the other human priests could pronounce her name the same way twice, so one of them just gave her the nickname Firefly, due to her fiery hair color, and it stuck.
She spent her time at the Basilica learning everything she could, staying awake at night while others slept. She saved up four years for her enchanted ring and loved every aspect of it. She only needed to spend two hours asleep on any given night and still be fully rested. So she used that time learning about far away places, locals to visit, odd trivia about exotic wildlife, and just about anything else she could read about.
Firefly was never one for practicing the martial arts. Swordplay came naturally to her and she could hold her own in a fight if need be, but she never practiced in the heavier armors like the other priests. Her teachers never pressed upon her to pursue that aspect of their way, considering how well she applied herself to her studies in her other areas.
It was on very good terms Firefly left in search of adventure, she had learned nearly all there was to learn by spending your time on one place. She was ready to learn by doing.
Father Nem, one of her favorite teachers, gave her a gift to help her on her way. A simple quiver by appearances alone, though he said she could use it for more than just arrows. It was a magically enchanted one capable of holding more on the inside than should be possible, with three separate compartments for all manner or storage. Once you stored an item inside one could just think what she wanted to draw forth and it would appear magically in your hand.
It was an incredibly interesting and valuable gift. Firefly thanked him and said she'd figure out how to make one some day and return his once she did. The priests mood changed suddenly and said that there was still more to give, though not a gift from himself.
He told her to wait a moment and went to his bedchamber. Firefly curiously peeked in as he slowly pulled an old and battered chest from under his bed out into the small room. Father Nem opened it slowly, Firefly couldn't help but gravitate into the room to get a closer look as he did so. Inside was a gleaming suit of Mithral that made metallic chinking noises as he placed it gingerly on his bed.
He told me that it was my mothers, and that she wanted me to have it when I was old enough to use it. He stopped my questions saying he was but a mere boy when he gave them to her, and new very little else. the sword was also hers and another gift she wanted me to have.
He retold a story of how it wielded great magic once, but it lost it's divine spark long ago. It now laid with no purpose, so became nonmagical.
She took them both. knowing there was a mystery to unveil someday.
