She's a college student, she can go for an inadvisably long time on caffeine and people not dying of old age.

The wizard outfit is delighted to have her.

It gets that far! For all they know her magic lets her go without sleep indefinitely as long as she has tea.

Alas, no. She can survive an all-nighter but she does call a stop after the session in which she notices the sun rising.

Okay. Would she like a hotel room? On the house.

...Maybe later. She would like to at least find out where her sister is sooner rather than later, actually.

"Where's that?" It looks like some kind of desert...

The scry's zoomed in enough to make out Illia, so it's hard to say. Deserts are mostly an Espaal thing? So maybe Espaal somewhere? It would be easier to tell if she were near civilization.

"...Either way, she's in a desert. And--she hasn't gotten to sleep at all, has she--I should have paid more attention to the time--can you get her here now?"

It'll take about an angle to draw up the diagram but the wizard will get right on that.

She really should have done this sooner.

The wizard soon has a diagram drawn up and calls Illia to the middle of a circle on the floor of his office.
