From Age of Sigmar - Lexicanum
| In all my travels across the realms, I have encountered no substance as widely coveted as realmstone. With it, mortals can bend reality to their will, raise shining civilisations from the wastes, or bring about untold ruin. Realmstone can grant you your wildest dreams, or give birth to your greatest nightmares. In short, my friend, realmstone is the perfect commodity.
