When she concludes her conversation with the Lord Marshal Cansellarion she conjures up a very fast horse and rides across the city at a pace that more Lawful cities would prohibit. She is expected at the Archduke of Sirmium's for lunch, but she is here two hours early for that.
Nonetheless she expects that if she dismounts in a similar hurry and tells his guard that she's there for lunch he'll hurry some lunch to a table somewhere.
The trial is in four hours.
