[X] Cython
I already think Mathilde is too invested in this library and spending too much time on it so having to take even more time out of our busy schedule to teach a bunch of locals or a newly-spawned spider hivemind is less than ideal in my book. Also, dragons are cool and Cython has a bunch of unique knowledge that he might be convinced to share with nagging visitors in order to make them go away.
The Gm made it clear that as long as we do not try to teach them kung fu or some other crazy thing we will have to spend no AP on teaching
