Etty follows, and picks up her dress, and shimmies into it, damp or no damp. "Will there be buckets?"

"Probably somewhere."

Etty starts looking.

The stable, while empty of horses, contains both buckets and blankets to spare.

Etty fills them all with water and brings them to the library door as (presumably) identified by Nona.

Etty follows her in and starts looking at the books hungrily.

There are a lot of books.

Are any of them about sorcery?

Most.

Excellent. Are any of them introductory-looking?

None.

Many of the books contain information on how to do spells, and the recipes seem reasonably complete; some are even annotated with the Baron's additions. But there is nothing resembling a book of theory, and very little organization to the spells themselves.

Etty hunts up something less cluttered than her well-used scroll to take notes on.

There is plenty of loose paper around; the Baron was also in the habit of taking notes.

Etty doesn't want to think about him right now. She takes blank paper and starts up an index of useful-looking spells with actionable recipes.

The Baron's much-used spell for serving himself meals is one that requires no long list of obscure ingredients for the setup, just a kitchen and a bowl of animal blood, and after that can be invoked at any time.

Can it be invoked by people other than the original caster, Etty wonders, or will she have to find an animal? (She would be squeamish about helping herself to a swan.)

No explicit information is included.

She decides to try the invocation step and see if it works.

The invocation step is to find oneself at a table one wishes to fill with food, and command - through word or gesture - that the table be so filled.

Etty goes. She sits at the table. She waves a hand - she really could stand to eat; it's been a while since dinner at this point - and stares down the emptiness of the table.

Nothing.
