Azorius Senate Guildmaster
Sphinx Supreme Judge (a.k.a. Your Honour)
"I serve only justice, but through that duty I serve all of Ravnica."
Isperia is a giant and wise Sphinx who currently controls the Senate. Her subordinates follow her word as law, which she makes the law anyway so it kind of is. She is extremely powerful and gifted in law magic, and precognitive magic.
