Nolwen is a Magcker, a magic hacker, who uses a pencil-shaped crystal to draw in the void to perform hacking incantations to steal information, block magic, obtain magic, or change a magic formula .
She takes the opportunity to program her headset, which allows her to better surf the magic web, but also to jam any surveillance system and camera so that she cannot be identified, while being able to detect any electronic device and magic spell nearby.
