Cora's necklace

This is the pendant that Cora wears on a leather thong around her neck. It's made of an nontarnishable silver material, and has a very small gem in each circular indentation. Ruby, sapphire, emerald, diamond, with a blazing fire- opal in the center of the piece.

She can't remember what it means, or even where it's from. The vast majority of the time she forgets she's even wearing it.  It's been with her, and a part of her for so long, that it's not even an afterthought anymore. It's just there.

It could be an ancient and forgotten symbol of balance and the sacred druidic tradition. Perhaps part of the reason she now remembers and picks up the lost art so quickly?

It could have simply been a reminder of her long-dead family.

If you ask her about it, she will react with surprise, and say honestly that she no longer knows anything about it.
