Breaking Hearts

Obtain seven mysterious spheres and bring them to Elena Zimina at the lower floor of the Mine.

Some little mechanisms are prowling around, but I don't understand what they are. Are they completely mechanical... or something else?
You know what's interesting? They have a small shining sphere, it's like it's their core or something. It looks just like the sphere that the creatures in the caves had! They are connected somehow, that's for sure.
If they are really Mechanoids, this sphere must be some kind of a battery. I think we should collect several samples since they are in our way.

Luville will kill me if we don't find anything interesting.

So... What has just happened?
I didn't understand anything. Did the sphere come alive? And it... grew a matter on itself? It created another Mechanoid? Or it wasn't a Mechanoid?
But how? I don't think machines can do things like that! Neither can living beings...
Maybe it's the final stage of the experiments conducted back at the Bestiary? Anyway, we shouldn't approach these spheres. Just crush them!
