Dragons

Hello everyone

So, i know there is a main dragon in this show, Longcurl. And I know there are 3 babies. But was there ever another dragon ? Perhaps one owned by Ravenhair. I seem to remember as a child, some type of dramatic incident that cause a dragon to breath fire. And my imagination might be fabricating this, but I think it had something to do with a choker around the neck of the dragon that was controlling him/her.
Does anyone remember something like this?

Thanks!
Sarah
