The Greek goddess of struggle, strife, and discord is Eris. She plays a critical role in various myths, often initiating conflict through her actions. One of her most famous incidents involves tossing a golden apple inscribed with "to the fairest" among the goddesses, leading to the famous competition that sparked the Trojan War. Eris embodies the disruptive forces of jealousy and rivalry, signifying how discord can influence the fate of gods and mortals alike.
