The Locus setting for the Star Ways can best be explained by the word itself:  a locality, a place, a centre or focus of great activity or intense concentration, or its mathematical meaning – the set or configuration of all points whose coordinates satisfy a single equation or one or more algebraic conditions, and finally, the position that a given gene or genetic marker occupies on a chromosome. For further information on the meaning of the term ‘locus’ refer to:

In short, the Locus of the Star Ways is the sphere which represents part of the ‘parallel’ world of the characters.  It is a state of existence off limits to humans and spirems alike, unless of course, that character has ‘celestial connections’.  The Locus also spirals in co-existence with the other two spheres of the Star Ways.
