21st century BC, Akkadian empire

Shu-sin, king of Ur, lived with his beloved wife, his children, and his brother Gilgamesh, who was known as the strongest in the land. When Shu-sin's son Ibbi-Sin was declared ready to rule, Gilgamesh went off on a great journey with many trials to find the source of immortality. The shade of his late boyfriend, Enkidu, begged a servant to intercede and persuade Gilgamesh off this path, but the servant had no such power to do so - or at least figured that she didn't.

The servant was called Enheduanna because of her eloquent speech at a remarkably young age, and no one was as surprised as her that she could speak to ghosts, let alone that she'd be solicited to speak to kings - mainly because she was an adolescent maid in service to Princess Kunsi-Matun. She followed Kunsi to Sirmanum, where she was to be their princess consort. Sirmanum rebelled, though, and chased Kunsi and Enheduanna into exile. In her helplessness, Enheduanna vented to Kunsi, sharing her observations of past kings' mistakes and triumphs, leading Kunsi to lead an army of her father's people to take Sirmanum. Her father then appointed his daughter as the rightful queen of Sirmanum.

A visitor to her kingdom stumbled into town on coronation day claiming to have seen a hidden world under the ocean.

His named was Aziz the Shepherd and he had written a journal full of what looked like gibberish in a made-up alphabet. Enheduanna, however, realized he was right. The royals threw Aziz into prison, but she visited him every day as the memories came flooding back to her.

Gilgamesh's journey ended in the same place as Aziz's.

For she "saw the secret, discovered the hidden, and brought knowledge from before the flood" and she would become the one who goes a great journey, pushing herself "to exhaustion, before being brought to peace."

But she disappeared from history and memory, same as the plant of immortality.
