It was an unsuccessful colony in the 23rd century, described as "doomed".
Solomon Kane was born at the Simka Colony, but was nominated for enrolment in Starfleet Academy by the colony's Federation Council delegate. That delegate was later indicted for several crimes, including corruption and selling influence. Kane also became a corrupt Starfleet officer and later pirate. (FASA RPG module: Orion Ruse)
- The Council delegate is only said to be "from a doomed colony in the Karion System" - it is assumed that this also refers to the Simka Colony, rather than a second colony in the same system. Given the histories of both Kane and the Council delegate, it seems likely that Simka Colony fell to crime and corruption.
