Here's what we know about them:
* They are a separate unit within the Dothraki army. They have their own traditions and customs, and they are not simply women who fight alongside men.
* They are highly skilled warriors. They ride horses, wield spears, and engage in battle just like their male counterparts.
* They are fiercely independent and loyal to their own. They have a strong sense of community and often fight for their own people rather than the khalasar of a particular leader.
In *A Dance with Dragons*, we primarily encounter the spearwives in the context of Daenerys Targaryen's journey through the Dothraki sea. They are often shown as strong and respected figures who are not afraid to challenge the authority of even the most powerful khals.
While the specific details of the spearwives' culture and traditions are not fully explored in the book, they are presented as a significant and fascinating aspect of the Dothraki society, demonstrating that women are not just passive figures within this culture but can play active and powerful roles.
