The ecology of Sky's Edge is superficially Terran, and includes recognizable plants and animals such as the hamadryad, but has been known to be metabolically incompatible with Terran flora and fauna, causing fatal anaphylactic shock in any creature or person who tried to consume it.
Sky's Edge was relatively backwards compared to most other human-settled worlds, as it possesses little in the way of high technology, and few can afford things such as the "immortality" treatments readily available elsewhere in colonized space. With perpetual war raging on Sky's Edge is the reason for this: the planet has exported little except a few biological products harvested from its extensive jungles, and most of its industries are already devoted to the war.
Trading ships stop by about once a decade, usually after being snubbed by traders in more lucrative markets such as the Yellowstone-Terra or Langara-Yellowstone-Hainia routes. The people of Sky's Edge rarely buy anything but weapons from the passing traders.
