I thought Mal was a necromancer and thorn was the rogue.
Ba-doom ching!

I am not the GM, and this is speculation on my part, but:
They are probably Ethereal. No amount of Perception allows you to detect the presence of Ethereal beings...because they're not actually present. They're in another plane.
The Gem lets you see into adjacent coterminous planes, like the Ethereal, so it would still reveal them there.
