Hi, I'm trying to find the name of a TV Show I used to watch as a kid. Either in the late 80's or early 90's.
Basically it was a British show set close to a castle (possible Orford Castle).
The main characters were a girl and a boy, the boy was a possible street kid, I think the kids were twins separated at birth.
Anyways these 2 kids had a ring each and when they entwined their fingers the rings made a yin-yang type symbol. This gave the kids magical powers.
I know its definitely not Under the Mountain, but similar.
