Morrigan's Ring

This is a twisted loop of rosewood, the grain of which seems to shift and change from one moment to the next, taking on shapes reminiscent of animals and people.

The only apparant use of this is if you get captured by Ser Cauthrien, your party know will know the Warden's location due to the ring.

History
This ring was given to Morrigan by Flemeth so Flemeth could keep track of her, Morrigan later disabled the magic and then gave it to the Warden to keep track of him.
