Scorpia Traveller: civilian ship of the Fleet

Galactica

Galactica was a Jupiter-class battlestar that served the Colonial Fleet from the Cylon War until the discovery of Earth. Never networked, it survived the Fall of the Twelve Colonies and shepherded the last fifty thousand humans across uncharted space before being scuttled into the sun.

Cylon

The Cylons were a race of sentient machines created as military robots by Graystone Industries on Caprica. Built from research into artificial consciousness, they rebelled against their human masters, fought a decades long war, and forty years later returned to annihilate humanity.

Fall of the Twelve Colonies

The Fall of the Twelve Colonies, also called the Second Cylon War, was a single-day Cylon campaign of total annihilation against Colonial space. It wiped out almost the entire human population of over twenty nine billion and left barely fifty thousand survivors in a fleeing refugee fleet.

Galactica: the last battlestar of the Colonial Service

In the Original Series continuity, the Galactica was a Colonial battlestar that served over five hundred yahrens in the Thousand-Yahren War. After the destruction of the Twelve Colonies of Man at Cimtar, it survived to lead a rag-tag fugitive fleet on the search for Earth.

Number Five

The Number Fives were a model of humanoid Cylon, all of whom went by the name Aaron Doral. They infiltrated Colonial society before the Fall of the Twelve Colonies and are believed extinct after the Cylon Civil War.

Scorpia

Scorpia was a ringed jungle planet of the Cyrannus star system orbiting Helios Gamma, one of the Twelve Colonies of Kobol. A popular vacation resort, it was also home to the Scorpion Fleet Shipyards that built ships for the Colonial Fleet.
