fantasy Looking for sub in a Fantasy rp

The Summary; This is all based on a dream I had about hunting unicorns with an elf companion. Thought it was an interesting base for an rp. I was almost killed in it when a unicorn stabbed me in the chest but instead of killing me it changed me into a vampire or an incubus or something. The next night when I was healed I turned on my partner and bit her in the neck, then I woke up. The original idea involves a female partner but Im bi-curious, so if you wanna give this story an erotic spin with two dudes instead dont be afraid to reach out either.  

The options; The dream involved a sparky little elf girl who can handle herself in a fight. If you'd rather play something else like a young wizard apprentice or a witch, definitely let me know. And feel free to share your ideas for a character who fits into this narrative. You can go for any backstory you want, as long as it involves meeting my character sometime in the recent past. They should be acquainted by the start of our story. I left a tiny option in the starter to maybe hook an idea for you, but you can totally ignore this if you want. 

And now

The story : 

Years have passed since the last Border Wars took place between the kingdomes of man. Many elves and dwarves were drawn into these battles and thus shared a hand in the ruin of many forests. These enchanted woodlands were once homes to many faeries, gnomes, and especially the illustrious DIREBEASTS, four legged terrors which resembled horses but with a single horn protruding from their skull. Hundreds of men and elf alike lost their lives for less than a chance to hold the horns of such powerful creatures. Legend told of the magical power these beasts weilded and there was hardly a wizard in the continent who wouldnt do anything for a chance to weild the creatures horns as a wand for their magic. And so, even after the borders were settled, bounties continued to be made. The horn of a unicorn could go for a king's ransome. Many have tried, and that many have died. To seek such a unicorn was to seek an almost certain doom.

Enter the hunter, [YN], and their human bodyguard Caleb Willard. They were both veterans of the last war, victims of its bloodshed which claimed the lives of people they loved. United by this commonality, the two decided to go into business together chasing the promise of gold from these unicorn horns. [YN] would prove to be valuable in these hunts. Even after all this time, they were still a virgin, which was the one thing keeping their chance of attracting a unicorn intact. Tainted horned beasts such as these were rumored to seek out virgins for the chance of stealing their virginities for themselves. As to why, nobody knows, but to use this knowledge has proven successful. With [YN] as bait, a trap would be set and it was Caleb who would step in only of he was needed. Such was hardly the case as [YN] was also capable in battle

The two have been on three hunts together, and two of those hunts were successful. The third beast got away from them, and so preparations for a fourth hunt were being made this night at the Prarie Ladies inn just shy of the furthest human kingdom. Caleb was in a bedroom he was renting from the inn, sharpening his speartip when [YN] walked in. The two always shared a room together, Caleb on the floor with straw and (YN) with their own bed to themselves. The bodyguard glanced up at them.

"Where were you out to this time? You were gone for hours..." He sighed, unsure if he was being too controlling. The hunter was capable and yet he was treating them like a doting older brother. He knew it was inappropriate but he spoke some justification for his pestering out loud

"You silly little rogue. How am I to be your bodyguard if I'm not to know your errands?" He says while returning to his task of shaving his blades sharpness. Fire from several candles licked at the darkness, casting Caleb's impressive shadow over the hunter. Even in all this darkness one could make out the history of Caleb's fighting in his face and torso. He had a scar that ran from his forhead to the left side of his shaved cheek. His long black hair was untied, making it harder to see the burn mark on the back of his neck where he was branded by a slaver before the hunter took him in. He was shirtless, making it easy for anyone with a light to see the scars on his back. Not all of it was from fighting, but most were. He sat there silently, eyes focused on his work while waiting for his hunter to combat him with a remark...
