When the bird descends, its actually the Palisman, Owlbert, that gives Luz warning. She looks up at the moth/bird, and staring at it a moment Luz could tell that this was not just an animal, but an Omen.

And it gave her another sheet, which Luz took and read aloud.

Help, and two names. She didn't know the two specifically, but she got the message loud and clear: they'd help in directing her toward who needed the help, unless the two names were people who needed the help? She'd find out soon enough by contacting them.

Hmm. She wondered a moment. Were there other notes like this?

Should she check?
