Was drawing a blank on what else Laura can do to prepare here. Especially as it feels like she might be approaching a check point where other business should be sorted out if possible.

I suppose she does need glamour so can be on the look out for an opportunity to feed.

Secondly, she ought to check in with at least one of her touchstones, and Monica is homeless so might have problems in addition to the possibility of being kidnapped by hobgoblins.

Other then that I don't think the King in Yellow is someone who can be researched beyond what Laura already knows about him. Unless you have any suggestions on that point.
