The lady in the iron mask (and her 'curiously lifelike statues') reminds me of a short story I read about a guy who falls for a mysterious woman he meets on a cruise off the waters of Greece.
They have a fling, despite her odd habit of never taking her headwrap/turban or sunglasses off, and it's only later when someone tries to mug them that she knocks him down and puts her hand over his eyes before whipping off her sunglasses and turning their attacker to stone.
Imra can definitely freeze someone with her gaze, too. In the case of Garth, she doesn't even need to use telepathy!
