The stone seals are six objects found by Aline Cedrac in Alone in the Dark: The New Nightmare.
The New Nightmare[]
The six seals represent the six Abkanis gods of light, and are found by Aline Cedrac in an underground Indian temple at the altars dedicated to the gods and accessible through an ancient machine that rotates the entire room. They should be inserted in six other altars in a building outside of the temple, in doing so an ancient mechanism will raise a stone slab, allowing Aline to retrieve the stone pyramid.
