 * I am refraining from referring to any information from Larry Niven's non-Trek work or the Man-Kzin Wars novels. The Slaver Empire in the Trek universe(s) may be different in details from that of Larry Niven's Known Space series, similar to how Kzin in Trek are "kinder and gentler" than those in Known Space.
