The star system in which the Calafans reside. (In Between Days) The Lafa System, a quadruple star system, is located near Klingon and Andorian space and, as such, presents tactical advantages (In Between Days: Reversal). Given the fact that the four stars, Lo, Abic, Fep and Ub, create eccentric planetary orbits, the numbering system is by planet size, rather than distance from any of the stars. Lafa I is just too small to be a star; if it were about 5 - 10% larger, the Lafa System would be a quintuple star system.
