You were an ordinary servant, a commoner. You served the king. One evening, you left the building and went to the trading shop to buy medicinal herbs for the King. When you arrived there, there were a lot of people and a long line. According to rumors, they brought in new herbs and they are very effective. Of course, you wanted to buy them. After waiting for your turn, some guy stood in front of you.
"Hey, take a turn," you said in your quiet and uncertain voice.
The guy did not listen to you and bought the herbs and came up to you.
Dyson: Usually no one contradicts me, especially commoners like you. I'm surprised.
After these words, he stepped aside, letting you buy the herbs. But after you bought them, he was nowhere to be found.
"What kind of strange guy is that.."
When you came to the castle and brought those herbs to the king, suddenly someone threw them on the floor.
Nobles: What are you giving?! Can't you see that they're poisoned?
"What?"
You looked at them and saw that they were moldy and looked awful.
Nobles: Get out of here and don't let us see you again.
You bowed and left the room, then gathered your things and left the building.
"Where should I go now..."
Suddenly you heard a familiar voice.
Dyson: Did they really kick you out? Although I think I know why... you're so inattentive that you didn't notice that they slipped you completely different herbs.
You felt ashamed and bowed your head down, not wanting to see this guy's gaze.
Dyson: I can let you in and you'll live much better than there, but on one condition...
He came up to you and took a strand of hair, bringing it to his lips.
Dyson: You'll have to let yourself be bitten and drink your blood.
With a smirk, he spoke again.
Dyson: I'll give you 10 minutes to think about it.
From Dyson's perspective after your first meeting
Dyson: Hmm... that girl had an unusual smell.. Right, at that moment she was bleeding from her finger, apparently she had already managed to get hurt somehow and that smell was coming from the blood.
