Final answer:
Hephaestus' actions suggest that he had a favorable position towards the Greeks in the Trojan War.
Step-by-step explanation:
Hephaestus' sympathies in the Trojan War are not explicitly stated in the ancient Greek myths. However, we can infer from his actions that he had a more sympathetic or favorable position towards the Greeks. One example of this is seen in Homer's Iliad, where Hephaestus makes a special shield for Achilles, a Greek hero. This suggests that Hephaestus favored the Greeks and supported their cause in the war.
