Wondering about wonders

[Martinus]

I knew I had heard Cynosure in other context, and after some little research, just got it:

Cynosure is other name for Ursa Minor, that is the Polaris/North Star constellation. It also means (due to association with this star) "one who guides", or "one who is center of attention"

It sounds like a Great Lighthouse equivalent, but not necessarily relating to seas (perhaps giving a bonus to satellites?). The association I get is with the Astronomican of the Warhammer 40000 world.
