Es'sca was first elected governor of planet Damiano in 2341, and served six five-year terms. Damiano joined the United Federation of Planets as Es'sca took office, and Es'sca led through a period when there was strong anti-Federation sentiment on its world. These problems were exacerbated when a prototype Federation probe, Starfly One Bioprobe, landed in the capital city Iaron, wrecking death and destruction on the city. (NF short story: "Oil and Water")
