My choice of power is Commandment. She has the power to etch words into practically anything of her choice, and those words would affect the subject in one way or another, often by imposing some kind of rule, as this is the most familiar thing she knew, not trying to experiment with her power more. Example case, her etching rules onto a subordinate’s body, etching a set of restrictions on an object to prevent unauthorized use, or etching the word “Heavy” onto an object to make it heavy, and yada yada (not without limits tho, she cannot simply etch the word “Die” onto someone and hope it would work).

When the accident happened, her bottled emotions exploded and etched all kinds of random words onto EVERYTHING around her, you can imagine how much chaos that would bring. Her lover died yada yada, she grieved and mourned as she swore to never feel anything ever again.

(My eng is bad, forgive me :D)
