Astra's bracelets

Astra's braceles are two bracelets made from her hair from the knots Levi and Rowen braided into her hair. They are courting braids that young Levi and Rowen that their mother taught them under the guise of'best friend' braids.

It would take the three of them many years before realizing they were courting braids rather than 'best friend' braids.

the braiding was the last memory the three shared before Levi and Rowen were kidnapped and taken to the King's zoo.
