Ah! Now that I can help you with. Spells are performed differently depending on the spell, but they do have some things in common: there's a short incantation and hand gesture that go with each spell, and you'll need to know the shinki name of the person you're casting it on.

There are a few simpler spells I know of, such as Bind, which prevents a shinki from moving, and Silence, which would prevent them from making a sound.

[He adds, tapping a finger against his chin:]

There are, I believe, quite a few others. Some of the new shinki know them; some of the experienced shinki are experts, and may be convinced to assist in our studies.
