Something's Sour in Svettla
An earth like planet settled by humans via large interstellar seed ships. A wide array of organisms have been seeded on the planet, primarly derived from native Earth organisms, though some are artificially constructed organisms engineered to terraform the planet prior to seeding with other entities.
Baseline humans and near human derivatives were later seeded around the planet. As a baseline world, technological development was artificially retarded to prevent the use of electricity, internal combustion engines, and large concentrations of humans. Following unknown events that culminated in The Fall, the forces or entities that prevented technological development for millenium no longer intervened in World affairs. Additionally, items recovered from The Fall provided an impetitious to develop new sciences and trades with in a very short period of time.
