The Ossians are an alien species, that part built and part grown the derelict spaceship that was discovered (with horrific circumstances) on LV 426, (Acheron) the middle of 3 moons that orbit the ringed gas giant Calpamos, this gas giant itself orbits Zeta 2 Reticuli in the constellation of "The Net", only viewed from Earth's southern hemisphere. On a logging device, found in the derelict vessel by workers from the Weyland-Yutani Corporation, it was discovered that the Ossian's home planet is the 4th from the star Gamma Triangulum, in the constellation of "The Triangle", viewed from Earth's northern hemisphere. Ongoing deciphering of the Ossian device, hopefully will lead the WYC to the home planet of the Xenomorph, the terrible creature that caused the demise of the Ossian spaceship and all of it's crew, and nearly all of the crew of the Nostromo. The Xenomorph's home world must be destroyed to make our galaxy a safer place.
We have now fully deciphered the logging device from the derelict vessel that crash landed on Acheron. (LV 426) The Xenomorph's home planet is the 2nd from Barnard's Star, which has a system of 4 planets. (WY 581,) we have now called Gorgonia, after Medusa the gorgon in Greek Mythology. I wouldn't advise going any where near Gorgonia, unless your vessel is fully armed with fusion bombs with the capability of imploding this nightmare planet.
