Anagalshu is the daughter of king Ana-sin-emid of Azupiranu, and the seventh wife of the sorcerer Akurduana. Due to being bound to a vessel made during the 'dark age' following the fall of the Akkadian empire, she speaks Akkadian and has no knowledge of time periods after.

She was gifted in marriage to Akurduana by her father, who wished to ally the mighty sorcerer for the benefit of his city-state. The ploy succeeded, and the sorcerer Akurduana used his powers to support the king in conquering two nearby cities.

At some point complications arose in the alliance. She knows that her husband came home, bleeding and with a furious temper, after visiting the king to work a ritual to banish a demon. He bound her to this vessel in anger, cursing her family and bloodline for their betrayal. She knows that Akurduana was betrayed by the son of the king—though she does not know what transpired between the two.

In her previous life, Anagalshu was an industrious and obedient wife, though she has a prideful side to her that comes out when she feels that her worth is not acknowledged. She is a a skilled weaver, knows how to ride, which plants and minerals to use to make dyes, and was taught at a young age to play the flute and pan-flute, and practiced dancing for her husband's enterainment.
