Talk:Su Song's Armillary Sphere/@comment-5782071-20170217004548

I like the artifact, but don't we have multiple armillary spheres? I could have sworn you've made several. And I didn't know they were used in mechanical astronomical clocks. Huh.

BTW, have you actually thought of how this artifact (or at least the large combination of them) killed Wolcott?

Additionally, if this artifact alone ​can allow for unconsequential time travel... why couldn't/didn't Helena just use it when she got her hands on it to save her daughter?
