Isibel wracks her brain - doesn't she know anyone whose name has a meaning she knows that could be useful in that language -

Oh yes. Yes she does.

She knows how to say Unicorn Knight and she knows which part of that phrase means "knight" and which part does not.

"I saw the - unicorn -" she says, gesturing back the way she came. Normally she'd go on - and I had cause to speculate about the carver - but she doesn't have any old language to compose such suggestive unquestions out of.
