There are two kinds of sisterstone: a light orange kind called dusk sisterstone, and a scarlet sisterstone, both created in the earth and stones around the Field of Maidens in Geb.1

Reciprocal field

When both kinds of sisterstone are within 15 feet, they create a reciprocal field—a strange resonance—that repels undead.1

Crafters cannot make single objects from both kinds of sisterstone, though they often make paired items of each type.1
