Now that you point it out I am also bothered.
Mathilde's KNIFE: Knightly Night Implement For Eliminations
It's a sword
(Alt: Knightly Night Implement for Foe-Execution)
Actually, even better: An entire family of names for the same sword-spell. So that everyone can personalize it for their own use? Because Mathilde couldn't settle on a single name? To piss off students studying for exams? Who knows!
F: For, Foe, Facilitating, Free, Forthright, Frightening, Fast, Frightful...
E: Elimination, Extermination, Excursions, Extinguishment, Exsangunation, Expression, Expropriation, Expeditions, Excruciation, Excoriation, Evasculation, Exertation, Experimentation, Enemies...
Just pick two and you have your spell! Mathilde's Knightly Night Implement for Facilitating Expression! Mathilde's Knightly Night Implement for Frightening Enemies, Mathilde's Knightly Night Implement for Facilitating Exterminations, the are so many possibilities that I'd get bored writing them down and write a program to do it!
And it gives me no indication that Mathilde was not involved in making it, and rather implies she took part in the making, otherwise why would she be obligated to eat her share.
Because she organized the entire affair. It's like putting your PI's name on all your research papers: Even if all they did was sign off on the grant money, they still get to be last author.
edit:
When they said there was no hope left, and that the endless armies of the Burrito Gods would consume the world, salvation arrived from the island of Ulthuan, as Teclis founded the Colleges of Tacos.
The Elves looked down upon the Colleges, as they believed that true tacos could only be created by masters of all eight ingredients single-handedly weaving them in harmony: Shell, Meat, Refried Beans, Cheese, Guacamole, Sour Cream, Lettuce, Onions. But Teclis departed from this wisdom and instead trained disciples of each
individual ingredient, reasoning that a single ingredient may only be able to create a complete taco in collaboration but would still be worth perfecting on its own! Tortilla chips, Nachos, Bean Dip, French onion dip, all of these may only be inferior relatives of the true tacos, but they are still delicious. And so the Colleges were born.
