Many of the same wizards who can reshape reality with a standard action need to be handheld through things like sharing their rope tricks with each other. In some ways coordinating Korvosa's spellcasters isn't that different from how she spends her office hours typically; the wizards skew older than her students but are approximately as likely to all-on-their-own think up out-of-the-box strategies like asking whether, if they need sleep so badly, and their spellbook is upstairs, they can prepare the spell out of someone else's spellbook.
The Dean of Abjuration doesn't know where her own spellbook is, it's being passed around. Some people don't turn pages by the corner and she thought it better for her heart if she didn't watch.
There is a type of person who can survive any hardship and set aside any level of mental anguish as long as people are relying on them.
Julaei Cangi is, by nature, emphatically not one of those people.
But at her level when she casts the spell heroism it lasts two hours, which works nearly as well.
After the Breaching Festival Julaei found herself sliding into a place where she cast heroism on herself six or seven times a day. And then she went a month where she stopped preparing it altogether, because the temptation to cast it was too great if she did. And then she made a rule for herself that she could prepare heroism as long as she never prepared it in a fourth-circle slot, and that's worked for her so far.
So it is that Julaei Cangi meets Cressida Kroft with the brave face turned on. She has 700 rounds left on the spell, and hopes to be asleep when it wears off. Hello Cressida Kroft I'm so sorry about Ileosa none of this is your fault no one thinks it is Ileosa is unreasonable what can I do for you?
