	If you are looking for a new star field you 
don't have to wait for a full galactic year.  For example
one of the most prominent stars in our skies is Sirus,
but it is a blue super giant that has a life time of only 
a dozen million years or so. 

	What is more, most of the stars in our skies
have rapid proper motions across our point of view. I
estimate that even 1/10 th of a galactic year would be
enough to completely change our skies.

	I'm not sure about your assumption that the
Mnoren didn't find any uninhabited planets. Let us say
they came across a totally uninteresting lump of rock
with no atmosphere or an unbreathable one. Would 
they count that as one of their 'worlds'?

	I always assumed that Cidri was on a Dyson 
Sphere.
