Sent 2: He continued to Illyria, where he sought refuge with the Illyrian King and was treated as a guest, despite having defeated them in battle a few years before.
Sent 3: However, it appears Philip never intended to disown his politically and militarily trained son.
Sent 4: Accordingly, Alexander returned to Macedon after six months due to the efforts of a family friend, Demaratus, who mediated between the two parties.
Sent 5: In the following year, the Persian satrap (governor) of Caria, Pixodarus, offered his eldest daughter to Alexander's half-brother, Philip Arrhidaeus.
Sent 6: Olympias and several of Alexander's friends suggested this showed Philip intended to make Arrhidaeus his heir.
Sent 7: Alexander reacted by sending an actor, Thessalus of Corinth, to tell Pixodarus that he should not offer his daughter's hand to an illegitimate son, but instead to Alexander.
Sent 8: When Philip heard of this, he stopped the negotiations and scolded Alexander for wishing to marry the daughter of a Carian, explaining that he wanted a better bride for him.
Sent 9: Philip exiled four of Alexander's friends, Harpalus, Nearchus, Ptolemy and Erigyius, and had the Corinthians bring Thessalus to him in chains.

Question: Paragraph- Sent 1: Imagine you are standing in a farm field in central Illinois.
