Tara smiles. "Okay." She gets them out of the case, and hands one of the rings to Morgana, slipping the other one on her finger.

"We've got a few empty rooms upstairs. I'll go up, pick one at random, and wait there. When you're ready, try to clear your mind a little, then touch the stone with one of the fingers of your other hand. It should help you focus. Okay?"

If the ring works like Tara intends, it will give Morgana a small visual flash of Tara's surroundings initially, and then a more visceral "tug" in the right direction, almost like a dowsing rod, stronger when she moves in the right direction.
