Do you think any civilisations have unlocked eternal life?

I'd say that if they created 'eternal life' (rather than merely extending life), then they probably have no need for harvest anyway. I am not assuming that the maintenance of the body, over long durations, is not reduced to just a chemical/technological creation. The body is ultimately 'a creature of the mind's creation' - regardless of the purely external maintenance of the shell. Because of natural increase in 'entropy' over time, its continued viability ultimately depends on the continued balance of mind in the face of catalyst.

Why do you think a clone would have the same emotions? It would merely have the same genetic predispositions, like twins. Even then the consciousness, use of will in different circumstances, determines gene expression.

Here's another hypothetical question: each planet is on its own harvest clock. What if a 3rd density civilization develops advance space travel and leaves the planet before harvest time, how would they be harvested.

interesting! i think they would be stopped by the guardians. then again if they weren't i imagine they would be able to postpone or escape the clock strike if they go away from the galactic center and toward the outer reaches.
