endeavored

Context:

There's a ritual he was looking for back in the seventeenth century. Apparently, a soul eater who emerged in the prehistoric era endeavored to become a god who was eventually worshipped in ancient Greece.

Is the end of the second paragraph correct?

The way I'd write it:

Apparently, a soul eater who emerged in the prehistoric era, endeavored to become a god, and was eventually worshipped in ancient Greece.

I agree. The original sentence is faulty. The soul eater did not endeavour to become "a god who was eventually worshipped in ancient Greece" (it only intended to become "a god") but that is what she has written.

The second "who" and the phrase it relates define "a god", but the writer meant them to define the "soul eater". She has already used one pronoun ("who") for the soul eater, though, and as you say, only needs to use "and".

Thanks.
