Womanstone

Womanstone is a mineral found on the world of Avyla. It is heat-sensitive, and changes colours depending on the changes in its wearer's body.

The Aelur females wear small pieces of womanstone as pendants once they have passed their tests. The ways such pendants are worn indicate whether a woman is looking for a mate or not, and how many children she has, if any. Elspeth Kolesar, an adopted Aelur, earns her pendant of womanstone at the end of Killdeer, and it is noted to work for her in the same way as it would for any born Aelur woman.
