Cornerlius has served many years in the Revenant's guild. As the most veteran member, he serves as representative of the guild when working with the rebellion. He seems supportive of the rebel's cause, but has made it clear that his true loyalty lies with his guild.
His work has earned the respect of many, but a fair number of critics as well. He first crossed paths with Sibyl and Ret when they joined the guild, and his knowledge of the world has been a valued resource since.
