I want to know the answer to the following question:
Who had now been appointed as a military advisor to the emperor of Seleucid?
All the background I'm provided with is that "The Seleucids were much stronger than the Macedonians had ever been, because they controlled much of the former Persian Empire, and by now had almost entirely reassembled Alexander the Great's former empire.". Is that enough to answer the question?
Answer: no
