LV-223

LV-223 (Varda) is one of three known moons of the gas giant Calpamos, located in Zeta2 Reticuli. The moon has a large system of mountains, deserts and valleys.

Climate
The atmosphere is composed of 71% of nitrogen, 21% oxygen, 3% carbon dioxide and traces of argon and other gases. The air on LV-223 is mostly identical to Earth's atmosphere, but contains a higher concentration of carbon dioxide (CO2) making it toxic for humans to breathe outside (Earth levels of CO2 currently average about 0.04% for comparison).

Species
It is uncertain if there were any existing life forms before the Engineers, but at some point a group of them constructed an outpost on the planet. It is suggested by Janek that it was some type of military base set up by the Engineers to build biological weapons before some incident compromised their operation. There is also a worm-like lifeform found within which is speculated to have been indigenous to the planet. After going through a mutation process, it's believed the worm-like lifeforms become the lethal Hammerpede.
