Where is Janus?

This is one of those head scratchers... I gave the system Janus is in the name Geminus (a title of the God Janus, that touches on the fact that he probably started as a twin being). The Star is suppose to be a yellow Sol type.<div><br /></div><div>The original material also states it is a bit off the main star routs, near someplace called Gergonise (I am thinking a system or planet with higher colonization level and space travel, so probably the route to Janus is from that point) &amp; Janus's sun is near &quot;the cluster&quot;.</div><div><br /></div><div>So Formad Cluster?</div><div><br /></div><div>Is there a Cluster off map?</div><div><br /></div><div>Do I junk the Cluster and just put it will it will work better?</div>
