Chase the spell-slinging bitch!

With no hesitation whatsoever, you snap into action, leaping to your feet and drawing your knife. You take a split second to pinpoint the witch's location with your finely honed ears, before sprinting off in that direction, dancing deftly over the handful of obstacles that litter the forest floor. Flashes of blue amid the green indicate that you're nearly onto her, and before long you're within leaping distance.

You jump forward and get the meddlesome mage into a headlock, knocking her to the floor and interrupting the defensive incantation she'd begun. You take the opportunity to get a better look at your harasser. She's human (that sets off alarm bells to begin with), but her skin is a little darker than most you've seen - must be from the North, you decide. You've heard tales of trickster witches from the North, and you don't like them one bit.

The one now struggling beneath your iron grip is shorter than you by quite a bit, with long, flowing black hair down to her waist, which is inexplicably completely clean - cleaner than it should be in this damn forest. She wears loose dark blue leggings and is barefoot; her top half bears only a simple band, also dark blue, around her chest, leaving her collarbone, shoulders, arms and midriff completely exposed.

You put your knife to the captive's throat and snarl into her ear. "Change me back. Now." But, to your surprise, she doesn't answer. She smiles.

It then occurs to you that the knife is basically an empty threat anyway, since you need her alive to change you back. This is an awkward situation you've got yourself into.

While you're thinking this over, the witch takes the opportunity to employ another gambit against you...
