I'm still curious about how this model (fails to) deal with Golems and elementalists since IIRC Mathilde has noted that between Bok and the elementalists the College model clearly has some fairly significant holes.
Elementals use magic that identifies with the four elements—earth, wind, fire, and water. Under the teclisian model, that is Hysh, Azyr, Aqshy, and Ghyran—but Earth elementals are not made of light. Hysh might be associated with earth, but if you get a lot of it together you don't get earth, you get light.
The "solution" to this is Earthbound magic—at low volumes, the winds lose their identity and you can sort of impose whatever identity you want on them. But Earthbound magic isn't strong enough to make elementals—and if you gather more of it, it stops being Earthbound and becomes Wind magic.
This creates a bit of a catch-22—earthbound magic is the only way to create an elemental, but it's too weak to actually sustain the enchantment. Not enough Hysh and it won't function. Too much and you have a light elemental. There's no level of "just right" to create earth, or water, or wind elementals (fire, of course, can come directly from Aqshy).
By all the known laws of magic, elementals are impossible. But they clearly exist, therefore we can deduce that the
known laws of magic are incomplete or even outright wrong.
