Talk:Cluster/@comment-25472353-20150323201130

I personally think she was just referring to the cluster of galaxies of which Earth's is included (IE, the Local Group). Her and Jasper probably had to keep tabs on that whole region of space.

It is interesting however that she mentions going to Earth specifically to have a look at the cluster. I'm guessing this has  something to do with Galaxy Warp--maybe Earth is something of a nexus for portals to the surrounding galaxies.
