Jill has always been a bit arrogant about her skill in alchemy. To the point where she would revel in revealing the errors others made. Her boasting caused her to enter into a bet with another alchemist on who could make the better alchemist’s fire. Jill worked feverishly to make a better version than that hack James Carder.
When it came time to demonstrate the effectiveness in front of the membership of the Alchemist Guild, Jill’s version fizzled. Furious to be embarrassed in front of the whole guild, Jill returned to her lab and discovered that James had mislabeled one of her key ingredients.
Making a new batch, Jill returned to the guild headquarters and proceeded to lob her new version at the entrances of the building, with a few for good measure at the surrounding buildings. As Jill walked away from the building firestorm, she smiled as she contemplated all those fools trying desperately trying to put out her improved recipe.
The fire ripped through several blocks of the city, killing hundreds and injuring thousands. At her trial Jill freely admitted that she was responsible and that her recipe was obviously superior to that of her now dead peer. She was sentenced to Death by Burning.
If she got the chance she would love to see all those fools burn for their ignorance of her greatness.
