Lost in Age of Science and later found by Arlen Bales in The Ruins of Anoch Sun, these wards are not only defensive against corelings but can injure them. They are found on the Spear of Kaji, and Arlen used them to tattoo his body with them. Later, he teaches them to others so that they can be put on their own weapons.
