Federico was a techno-mage, apprenticed to Herazade.  Federico is one of the most outgoing characters amongst the technomages. He is easily delighted and popular with the female mages. When the circle finally elects new members at the end of the shadow war he is the youngest ever to climb their ranks. Technically still an initiate. Federico liked to be called Fed, though Galen was somewhat "uncomfortable with the familiarity of the diminutive." (That seems to change after Galen's return from Z'Ha'dum) He reminds Galen of a pirate, with wild hair and beard, in colourful robes.
