Schism
The Schism is a nebulous, ill-defined event (or series of events) that brought about the collapse of humanity's original empire. Pre-Schism society is thought to be responsible for a lot of the weirder shit in the setting; there's more than one school of thought that considers psionors to be a result of genetic experimentation thousands upon thousands of years ago. Pre-Schism humanity was absurdly technologically advanced, second only to the Uclasions, whose technologies they'd adapted over time.
The Schism probably occured about 10,000 years before the Common Era. Although frankly nobody knows for sure.
