I've come to 2 different options, but decided on this answer because I believe it has closer clues.
We are the mythical twins
Quetzalcoatl and Xolotl, mythical twins
In the in-between place
Gateway to the middle
They are in the underworld but want to escape and create a life
Where the king's daughter faces the dust
We are of the strong one, the labourer
While trying to run away from the underworld, Quetzalcoatl dropped the bones, and they broke into pieces. He gathered up the pieces and took them to the earth goddess Cihuacoatl, who ground them into flour. Quetzalcoatl moistened the flour with his own blood, which gave it life. Then he and Xolotl shaped the mixture into human forms and taught the new creatures how to reproduce themselves. So I guess Cihuacoatl represents the holy woman, and since twins do the hard work, they are the labourers.
One of us keeps monkeys
Quetzalcoatl: In his form as Ehecatl he is the wind, is represented by spider monkeys, ducks, and the wind itself.
