Dazrin is correct. I believe it was explained towards the end of Ruby Knight. Seraphina (sp) explains it around the time they retrieve the jewel. And if she doesn't explain it then, she explains it at some other point in the series when she's talking about how the Elenians got the rings in the first place. IOW, it might be in the next trilogy.
