Es'sca G'ullho was a Damiani politician in the 24th century.
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")
Es'sca did not run for re-election in 2371, and was succeeded by his chief of staff, Ra'ch B'ullhy. (TNG comic: Perchance to Dream: "To Take Arms Against a Sea of Troubles")
