This Faerie is Kari's assistant. When Kari is away from the Neggery, her apprentice takes over her duties. In 2012, she found a mysterious book detailing the quest to hide the Clockwork Negg.
Hi, Kari!
From the beginning! I was why the shopkeepers called you to volunteer their help in the first place.
As soon as we heard about Orion, I knew you'd need help this year, and, well, I also wanted to try and cheer you up. I see how happy you are when the Festival of Neggs has a puzzle to solve, and so I thought this would be a fun way to thank you for all the hard work you've done over the years! Plus, I thought a little mystery would be fun with all the mayhem going on in the world.
Of course I remembered! I'm your apprentice. It's my job! Plus, I've been so worried about you. You saved me all those years ago, and yet I feel like I haven't done nearly enough to repay you. And now, I can't even help you when you need it most.
Really?
I... I would love that!
It is implied that Kari saved Zaira from some undisclosed fate prior to her becoming an apprentice.
