The most capable of the Satrap's Companions, whose intelligence and political acumen are deployed in service of a ruler who cannot make proper use of them. Serilla's arc in the Liveship Traders Trilogy examines the particular frustration of competence trapped within structures that deny it expression, and her role in Bingtown's political crisis gives her unexpected agency. Her relationship with power - what she wants from it and what she is willing to do to obtain it - becomes increasingly complex as the trilogy progresses.
