i am capable of anything

The following has been taken from The Black Jewels Wiki until I get around to writing up my own profile for Janelle. Minor spoilers ahead; I've removed the major ones.

General: Jaenelle Angelline (pronounced "Jah-nell" with a soft "j") is the protagonist of the Black Jewels Trilogy, the most powerful Queen in Blood history, and Witch. Jaenelle's Court is referred to as the Dark Court. Her Birthright consisted of thirteen Black Jewels and a Jewel of every color before that, to cut her Craft baby teeth on; after making the Offering to the Darkness, she obtained six Ebony Jewels. She is one of the rare triple-gifted witches, as she is a Queen, a Black Widow, and a Healer, all naturally.

Powers and Abilities: As an incarnation of Witch created from the wishes of several races from Terreille, Kaeleer and Hell, Jaenelle is an extremely powerful being with near god-like powers that far surpass even other Black-Jeweled Blood members such as Cassandra, Saetan or Daemon and even previous Witch incarnations. She is one of three triple-gifted Queens, meaning she is a natural Healer, Black Widow and Queen. In all these castes Jaenelle has been noted to be far more powerful and skilled than her peers. Due to her immense powers she has been noted to have troubles when performing basic Craft (such as summoning her shoes) due to her inability to use the small amounts of power required for the basic spells.

From a young age Jaenelle received an eclectic upbringing, and as such she is immensely skilled in a variety of areas, from various forms of dancing and music, to producing Craft spells, to being trained in armed and unarmed combat. In this last one, she was tutored by various skilled warriors like Chaosti, Prothvar, Andulvar and Lucivar. As such she is skilled with several weapons such as Eyrian ones to the point where she has beaten Lucivar in sparring matches on more than one occassion. She has deceptively high levels of strength and stamina, as she was able to go on a non-stop three-day run on the mountains of Askavi when under the effects of safframate, hold an Eyrian war sword (which were noted to be very large and heavy) and crush an axe handle with her bare hands. As Witch, the Old Tongue is her native language and as such her understanding of it is superior to every other character in the series, including Saetan.

Queen: As a Queen, she is extremely skilled, capable of attracting powerful Blood members such as Warlord Princes and even other Queens into naturally following and serving her even at the cost of honor or ties to others (Saetan once noted that if she wanted, he would force the Realm of Terreille into submission), though she is too kind to force someone to such acts. She has been capable of forcing dark-Jeweled Warlord Princes off the killing edge with a simple call to her service. With these abilities as Queen she was able to create a Dark Court from almost all of the Territories of Kaeleer. As a Queen her primary ability is her connection to the land itself, and the ability to maintain the land purified and fertile.

Black Widow: As a Black Widow, her ability to weave Tangled Webs in order to receive visions of the future is extremely accurate and all-encompassing and is likely second only to the abilities of the Aracnian spider-Queen (although even the Aracnian spider-Queen noted that no one weaves a tangled web better than the Witch even though not even she can sense all the smells from the threads). She is also capable of creating powerful illusions ranging from inanimate objects, to living beings; this later ability is know as a shadow, and Jaenelle's shadows are elaborate enough to pose as actual people. They possess limited thought process, are capable of casting limited spells and can physically touch someone (though the person is unable to touch the shadow). She is also capable of producing and countering poisons. Lucivar, an Ebon-Grey Jeweled Eyrian Warlord Prince noted that the potency of Jaenelle's poison on her serpent tooth could kill him twice in a row.

Healer: As a Healer she is superior to other Healers, capable of healing extensive injuries and curing people from powerful poisons. She would regularly make powerful tonics capable of even restoring demon-dead and Guardians to a near-equal level of power closest to when they were alive.
