Age of Sigmar RPG: Soulbound – Core Rulebook
The Soulbound are an ancient order dating back to the Age of Myth. During this time the Pantheon of Order created the Soulbound as both servants of the gods and guardians of the Realms. As the Pantheon of Order shattered and the Mortal Realms descended into the Age of Chaos, the Soulbound faded into memory. Now, in a time of utmost need, Sigmar has called on the other gods to join together and resurrect the lost order. Many ignored the God-King’s call but some answered, and now the Soulbound once more walk the Mortal Realms.
