If they didn’t, they wouldn’t be worth spending time with at all! I must admit, I’m not entirely sure what to picture. When you say gems, what I think of is the precious stones that nobles put on their jewelry, but just from what they can do, I’m sure they’re much more than that!

Sounds close enough to me, but then I’m no noble. You sound like you’ve got quite a few tutors. Violin and tennis are more things I’m not really familiar with though.

[Pod’s answer is as amused as a thought can be.] That’s what folk call them. They’re not quite like the familiar of a witch or a mage; they’re so much better.

In my opinion, anyway!
