Ertrax

Ertrax was a Wild Space planet located within the star system of the same name. It was home to the Ertraxi, a peaceful species of multiple-eyed humanoids. At some point during the reign of the Galactic Republic, a Republic starship crash-landed on Ertrax, leaving no survivors. The Ertraxi found the wrecked vessel, repaired over the span of several years, and eventually flew it off-planet in search of other species.

Shortly after that, a group of explorers found a trail of Cronau radiation left behind by the Ertraxi starship and followed it, leading them to discover Ertrax and make first contact with the aliens. When the group brought news of their discovery back to the wider galactic community, the explorers learned that the information spurred many opportunistic traders and slavers to travel to Ertrax in order to exploit the newly-found world. The explorer group then returned to Ertrax and warned and armed the natives, at the same time assisting them with gaining a Republic membership.

Behind the scenes
Ertrax was first mentioned in Scum and Villainy, a 2008 sourcebook authored by Gary Astleford, Robert J. Schwalb, Owen K.C. Stephens, Rodney Thompson, and J.D. Wiker. Within the book, the planet was described in an adventure seed for use with the Wizards of the Coast Star Wars Roleplaying Game, which this article assumes plays out as described. The 2009 reference book The Essential Atlas placed the Ertrax system, and therefore the planet Ertrax, in grid square N-21.
