Tomik Vrona is a security mage from Ravnica, who specializes in contracts, verbal agreements, and barriers protecting physical treasures. He is part of the Orzhov Syndicate, and the former apprentice of Teysa Karlov.

His parents were infamous advokists and oligarchs within the guild. When they died in an accident, they were quickly turned into spirits and continued to raise their son. Tomik grew up with a respect for the law that is unusual among the Orzhov, along with an appreciation for clever loopholes that is very much in character for the guild. His apprenticeship under Teysa Karlov has helped him build a career out of his talents, and during her imprisonment he had become her lifeline to the outside world. He operated as her right hand, running messages to her old contacts and fostering secret alliances.
