Diplomatic action
As a judge, Isperia had once issued a writ of mass arrest for any and all members caught bearing allegiance to the Golgari Swarm. Vraska was amongst those apprehended, and they were taken to an Azorius detention compound, the place where all victims of the writ had been imprisoned. Unfortunately, the cells quickly filled beyond capacity and, vastly outnumbered by their prisoners, the Azorius were swept under the tide of a prison riot. These events became known as the Duskend Troubles. Nearly one hundred were killed, many while still in custody.
Isperia was the guild champion before she replaced Augustin IV. Like other sphinxes, Isperia was aloof, wise, and valued solitude. The process of convincing her to lead the guild took years.
Isperia was devoted to her guild's belief that law is the ultimate bulwark against chaos.[8] As guildmaster she served as the supreme judge, taking advantage of her encyclopedic knowledge of Ravnica's labyrinthine legal system. If an event turned violent, Isperia refrained from using lethal force if possible, preferring to subdue a wrongdoer so that the legal system could mete out justice.
