Raven is completely unaware of these powers. For now.
⛧ Powerful sixth sense — Raven can sense that there’s something off about someone (ie. the immortals, especially vaympires and weyrwolves) but doesn’t quite know why and how it is she feels this way.
This power doesn't tell her who’s what ---- as that would be too much ---- but each species has a different... feeling to them. Vaympires make her feel like there’s an empty spot in her chest and she gets a lump in her throat. Weyrwolves give her this feeling of breathlessness and itchy skin, especially around her fingernails. Syrens give her the feeling of having a dry mouth and she usually feels very thirsty even when she’s not. Wytches are the ones that make her feel the less due to how much exposure she had to them growing up, though they still make her feel strange, an indescribable feeling of not being right. Due to her distrusting nature and how it makes her feel around anyone, Raven doesn’t think much of it.
⛧ Power Augmentation — Her mere presence makes those (who have powers) around her more powerful, in whatever way; for wytches it might be enhancing their powers and for weyrwolves and vaympires, it might be enhancing their strength and their powers —- the ones affected can feel it.
Anyone in a five meters (sixteen feet) radius gets exposed to her power. Just by standing within that radius, the immortals around Raven will feel as if they have more energy. Raven, on the other hand, depending on how long she gets exposed to immortals, will start feeling worn out and, in more extreme cases (like direct touch) will make her feel woozy after a while.
Normally, a couple of hours (sometimes three, depending on how many are there) of standing presence is enough. At the end of those couple of hours, she will start feeling tired and sleepy. This high tolerance was developed through years and years of living with her family and it doesn’t take her too long to recover.
The more experienced immortals might feel this surge of energy in them, as if they got charged up in five bottles of energy drinks, but will still be able to keep their abilities and powers under control. Any immortal that don’t have their powers and abilities completely under control might be unable to fully control them.
There is one way to get more energy from Raven and that is through direct touch. Prolonged touch (about ten minutes), with or without the intention of getting more power, will drain her of energy within that time and Raven will get woozy and might even pass out of it goes one for more than ten minutes. It takes her about thirty minutes to charge up from this type of contact.
There is two ways for Raven to not let her energy get worn out every time she stands in the presence of immortals or gets touched by them: one of them is to be completely distracted by something that makes her feel more energized/content and it’s a random and involuntary occurrence that depends on what she’s doing/who she’s with. The other one is to imagine herself inside a glass box, a bubble, anything that would surround her completely and shield herself from energy leeches. It would take a bit of practice and full concentration and Raven doesn’t know of its existence.
