[s]No, some have enchantments, some don't...very rarely do they get humanoid forms, unless aided by a mage gifted with specific magics. Very rarely do they have magic strong enough to have a humanoid form, and[/s] any being with a humanoid form and strong magics are probably students. That being said, I over complicate things. In the walls of the academy, all of the familiars can choose to assume humanoid forms. None of them have strong magics of their own, though. Save for epic face puss caterpillar, who refuses to assume a humanoid form in front of the lesser beings, but also is actually secretly strong in magic.
