Antila is a delta-class planet in the A4477 system.
Unbeknownst to the Colonials, a group of outcasts from Scorpia had settled the planet many yahrens before the final Cylon attack against the Colonies. Some of the original settlers died from diseases native to the planet while others died from wild animals and the elements, but their settlement thrived until division, corruption, and malaise affected the Scorpion pacifist colony.
Sometime before the Cylon attack, the Cylons invaded Antila and managed to overtake the human settlement. Some survivors, like Megan had been captured, while others had fled—some had fled to the hills, away from the Cylons, while a score of children (lead by Kyle) began guerrilla warfare against the invaders. However, the reptilian Cylons had died out, being extremely susceptible to the virulent diseases on Antila, leaving Spectre in charge. To cover the failure of the invasion, the ambulatory sentience built machine facsimiles of Cylon Centurions, which he names after attributes of the planet (Mudhole, Hilltop, Treebark) and programs them to be subservient to his will in the hope of one day ascending the ranks of the Cylon Empire.
Starbuck's forced landing on Antila changes the tide against the Cylons. Despite Kyle's attempt to exchange Starbuck for his mother, Megan, Starbuck manages to force Spectre into retreating from the planet with the aid of Kyle's band of "young warriors". Megan, freed Antilans, and the children are reunited and rebuild their settlement with the help of the Cylon robots left behind by Spectre and lead by Hilltop. After this, a shuttle from Galactica recovers Starbuck and ferries him back to the Fleet (The Young Lords).
