But magic is neither good nor evil. It is a tool, like a knife. Is a knife evil? Only if the wielder is evil.

Hecate, to Hazel in The House of Hades

Hecate, goddess of magic

Mystioknesis, or reality warping, is the ability to control a natural form of energy, for example: creating snow, changing the weather, turning other people into animals, etc. Thus, giving it control over everything and everyone. Magic is a very complex and dangerous force as it gives control of natural energies in order to produce a needed positive change, but also could be used for evil purposes. Hecate and her children are especially skilled at this form of manipulation.

Percy Jackson and the Olympians

The Sea of Monsters

When Annabeth and Percy wash up on C.C.'s Spa and Resort (run by Circe, a daughter of Hecate, the goddess of magic and Helios, the Titan of the sun and fire) Circe turns Percy into a guinea pig, along with several other people (including the pirate Blackbeard and his crew), using her potion. She offers Annabeth the chance to stay on the island and become an immortal sorceress like herself. Annabeth ultimately declined. Annabeth then gives Percy, the guinea pig, and the other transformed humans some of Hermes' multivitamins, returning them to their normal selves.

The Last Olympian

Hecate associated herself with the Titans during the final battle of The Second Titan War. To prepare the battleground, she casted a spell around all of Manhattan to put millions of mortals to sleep and decelerate time which, together with Morpheus' ability, prevented mortals from entering the place of battle. Hecate also tried to break through the wards of Olympus, but failed as the wards on Olympus were too powerful.

The Heroes of Olympus

The Lost Hero

During Medea's fight with Jason Grace, Leo Valdez, and Piper McLean, she showed her magical abilities, as well as boasted about how Circe taught her magic. During a meeting of all the cabin counselors, Lou Ellen magically removed Miranda Gardiner's nose from her face, and Miranda was trying to get it back. She failed until Chiron told Lou Ellen to give Miranda her nose back.

The Demigod Diaries

Son of Magic

Lamia and Alabaster C. Torrington both showed a high level of skill in this power as Alabaster was mentioned to be the most powerful demigod child of Hecate. They fought each other with incantations, and Alabaster was, at the end, about to destroy Lamia with a spell before Hecate separated them, not wanting her children to kill each other. Finally, Howard Claymore was returned to the world as a Mistform after he died, by Hecate. Lamia mentioned having crafted a spell that gave monsters the ability to smell demigods. Claymore stated that if you put enough power behind an incantation, it can come true. 

The House of Hades

Hazel spends most of the book learning to use Mystiokinesis. The first time she successfully uses it is when she and Jason defeated Sciron. She then uses it against Pasiphaë, manipulating the magic of the Labyrinth so she and Leo could defeat her.

The Blood of Olympus

Hylla mentioned that some of her followers are Amazons and it was easy for them to send Nico di Angelo, Reyna, and Coach Hedge off course stating that Shadow Travel is magic. Lou Ellen and the half-bloods of the Hecate Cabin were stated to be protecting Camp Half-Blood with magical boundaries to slow the impending Roman invasion.

The Trials of Apollo

The Hidden Oracle

The Athena Parthenos attempts to protect Camp Half-Blood from the relentless onslaught of the Colossus Neronis automaton (which is shown to be more than twice the Parthenos' height), but the colossus ultimately breaks through the protective border.
