Terra Nova
The Second Human Extrasolar Colony
Terra Nova was the second human extrasolar colony and the first settled beyond the Charon mass relay, a garden world whose platinum deposits drew a rush of immigrants. Once the most populous Alliance colony, it later suffered batarian raids and a Reaper landing during the war.
Terra Nova was a garden world that became the second human extrasolar colony and the first settled beyond the Charon mass relay. Discovered in the first wave of Systems Alliance surveys in 2150, it grew slowly until the discovery of rich platinum deposits triggered a rush of immigration that briefly made it the most populous Alliance colony. In later years the threat of batarian attack drove many settlers away, and during the Reaper War the world fell to a Reaper landing after a brief naval battle.
Discovery and settlement#
Terra Nova was one of the Class-1 colonization prospects discovered by the first wave of Alliance surveys in 2150. It became the second human extrasolar colony and the first established beyond the Charon mass relay, a distinction that placed it at the frontier of early human expansion. The world was banded by a harsh equatorial desert, but the regions closer to its poles were temperate and habitable, and a colony took root there. The capital city was named Scott.
The platinum rush#
For its first decades the pace of development on Terra Nova was modest. That changed in the 2170s with the discovery of extensive deposits of platinum, a rare metal required in the clean burning hydrogen fuel cells that powered private vehicles. The find triggered a platinum rush, drawing immigrants and investment from throughout Alliance space and producing roughly a thirty percent rise in population over twelve years. At its height Terra Nova boasted the highest population of any formally endorsed Alliance colony.
Decline and the Reaper War#
The world's fortunes did not hold. In later years the persistent threat of batarian attack caused many colonists to emigrate, draining the population and making the name of the surrounding Exodus Cluster grimly fitting. When the Reaper War reached the colony, the Alliance's Sixth Fleet fought a brief battle for Terra Nova and then retreated, aware it could not win and hoping to regroup with allies and retake the world later. The Reapers landed and occupied the planet. Intelligence indicated that the Reaper force there was light, and debate followed over whether the world could be liberated or whether such an effort would prove futile against fresh reinforcements.
Frequently asked questions
- What is Terra Nova?
- Terra Nova was a garden world that became the second human extrasolar colony and the first settled beyond the Charon mass relay. It was discovered in the first wave of Systems Alliance surveys in 2150.
- What triggered the platinum rush on Terra Nova?
- For its first decades development on Terra Nova was modest, until the discovery of extensive platinum deposits in the 2170s. Platinum was valued because it was required in the clean burning hydrogen fuel cells that powered private vehicles, and the find drew immigrants and investment that produced roughly a thirty percent rise in population over twelve years.
- Why did people leave Terra Nova?
- At its height Terra Nova boasted the highest population of any formally endorsed Alliance colony, but in later years the persistent threat of batarian attack caused many colonists to emigrate. That decline made the name of the surrounding Exodus Cluster grimly fitting.
- What happened to Terra Nova during the Reaper War?
- When the Reaper War reached the colony, the Alliance's Sixth Fleet fought a brief battle for Terra Nova and then retreated, aware it could not win and hoping to regroup and retake the world later. The Reapers then landed and occupied the planet.
- Could Terra Nova be liberated after the Reapers landed?
- Intelligence indicated that the Reaper force on Terra Nova was light, and debate followed over whether the world could be liberated or whether such an effort would prove futile against fresh reinforcements.

Mass relay
Mass relays were colossal transit devices scattered across the Milky Way that flung starships across thousands of light years in moments. Long credited to the Protheans, they were in truth built by the Reapers as part of a trap meant to shape and harvest galactic civilization.
Reaper War
The Reaper War was the galaxy-wide conflict that began in 2186 when the Reapers emerged from dark space to harvest all advanced organic life. It saw the fall of Earth, Palaven, and Thessia, the forging of unlikely alliances, and a final battle over Earth that decided the fate of every species.
Reaper
The Reapers were an ancient race of synthetic-organic starships that hibernated in dark space and returned once every fifty thousand years to harvest the galaxy's advanced life. They built the Citadel and the mass relay network to guide civilization down a predictable path, then reaped it to preserve organic life from synthetic destruction.
Arcturus Station
Arcturus Station was a five kilometer space station that served as the military and political capital of the Systems Alliance from the First Contact War onward, guarding the mass relay to Earth. During the Reaper War it was abandoned and destroyed, becoming a grave for the 45,000 people aboard.
