Although they did not provide their names, Dolins and Theodore made Rorge’s acquaintance in a Flea Bottom alley in 283 AC. Rorge was tipped off by a dirty child that the two travelers may have money when they attempted to make their way to Rhaenys’s Hill through the alley that houses Rorge’s fighting pit. In a thinly veiled intimidation they were told they were welcome to fight in the pit anytime. Calaila observed this exchange but escaped Rorge’s notice.
