So, as he is 1000+ years dead at time of canon and mainly exists as part of Favien's backstory, rather than writing a character profile for Saba, I'm just writing his story right now so uh here's part one I guess, more soon probably.
The night after their wedding and Jasper's appointment as God of Nature, Favien and Jasper are lying together in bed, Favien stroking Jasper's hair and Jasper gently tracing the veins in his wings with a claw.
"How did you get this scar? You don't have any others, so why didn't this one fade?"
"Oh, I got that before I stopped aging. Couldn't have been much more than twenty years old, I think. Crossbows are quite dangerous when mishandled, you know?"
The sprite giggles and looks up at his new husband's smiling face, "You don't expect me to believe it was an accident do you? What happened?"
"I- it's- It's a long story."
"We have all the time in the world," he pressed
"It's really not that interesting," Jasper's ear twitches as he shifts to more comfortably meet his gaze, a slight frown casting an unspoken accusation.
"Oh, don't look at me like that," he lets out a deep sigh, "Look, it- concerns an ex-lover. My first, actually. I never really got over losing him" Favien murmurs.
Jasper reached out to stroke his cheek, "If it brings back painful memories, you don't have to tell me."
"No, it's okay. It's already been brought up so I might as well. And besides," he adds with a sly grin, "I've never been one to leave a man as handsome as you unsatisfied."
"You only ever have one thing on your mind, don't you?"
"Always, Darling, always." he continues, "So, do you want to hear the story?"
Jasper nods and falls silent, laying his head on Favien's bare chest.
"Okay uh..." he trails off, staring at the ceiling in thought, "I was born on Earth, my family lived in a forest near a seaside village which, if I recall correctly, would now be in France. It's beautiful, I'll have to take you sometime.
My parents, of course, warned me to stay well clear of the humans as they had always been a volatile, superstitious bunch and our little tribe had been attacked and forced to relocate several times before. I paid little heed to their advice. I never was the obedient type.
I was exploring near the forest's edge, much closer to the village than I should ever have been, when I found a secluded clearing with a stream-fed pool and there, bathing in the crystal clear water, I saw the most beautiful man I had ever laid eyes on. He had fair, unmarked skin that told me he'd never worked afield a day in his life, but I figured he must have been a trained fighter or perhaps a hunter to have such impressive musculature. He was built like a daydream, broad and toned with golden curls that fell to his shoulders and close-cropped stubble.
Until I saw him, I didn't even know I liked men. I'd never in my life felt such attraction. He truly took my breath away."
"Your first lover was a human?" Jasper interjects.
Favien nods, "Mmhm, and a noble at that. Though I can't tell you what kind of power he held, I still know nothing of human politics."
