Enchantress concept art.

Eirena, the Enchantress, has the most shadowy and ambiguous lore out of the three followers; she follows a mysterious figure called The Prophet. It's understood that the player will learn more about her dark past as they progress through the main story.

"Eirena’s mastery of enchantments and steely bravery in battle belie her youth – but the truth of her origins reconciles these qualities.

Eirena hails from the distant era of the Mage Clan Wars, where she was part of a clandestine sisterhood of magic-users known as the Hand of the Prophet. When the leader of the sisterhood, the eponymous Prophet, foresaw a great disaster that would occur fifteen hundred years in the future, Eirena and her sisters pledged their lives to preventing the tragedy. The sisters’ pledges were far from mere words, and the Prophet placed the entire sisterhood in a magical slumber to preserve them until the appointed time.

Recently, Eirena awoke to find herself in a world of portents and turmoil, a land vastly changed from the one she remembers. Her sisters are dead, and the Prophet is nowhere to be found. Despite the shock of her situation, Eirena’s purpose is clear: she has given herself over to a new age in the hopes that she will discover its salvation. Could her uncommon magic prove to be the key that will help you expel demonkind from Sanctuary?"^[0]
