Town
I'm not sure what you envision for the town/city Mike lives in.  I see it as a small, touristy place in the mountains of Colorado.  What do you think of the name Celes Peak... named for the fact that the natural rifts to Celestria are nearby?  Though no Terrestian would know that was the reason for the name and it's changed through the years dropping the ...tria.  Now this isn't set in stone if you want something different... none of it is set in stone yet.
