The religion began when an ancient scribe bled upon the surviving crimson heart-scale of Ignisvorn, the slain Celestial Dragon of primordial fire. Ten Progenitor Dragons emerged from the relic, five Chromatic and five Metallic, and the first dragonborn arose where the scribe's tears mingled with divine blood upon ash. Over generations, the descendants of those Progenitors became the Sacred Houses of Draknaar. The Covenant formed as both a faith and a political compact, claiming that the ten bloodlines must preserve Ignisvorn's legacy even while disputing what that legacy means.

Before history, Ignisvorn burned as a celestial dragon whose body was a living sun. A mortal paladin destroyed his form, but a crimson heart-scale survived. When an ancient scribe's blood touched it, ten Progenitor Dragons emerged. The first dragonborn arose from the scribe's tears mingled with divine blood upon ash. The Covenant teaches that every dragonborn carries a fragment of this original inheritance. The world is a cooling ember of Ignisvorn's former body, and the ten Progenitors are competing interpretations of what the slain sun intended.

The Covenant is organized around the Ten Sacred Houses, each claiming descent from one Progenitor Dragon. The houses are divided into five Metallic lineages and five Chromatic lineages, but all recognize Ignisvorn as their supreme ancestor. The Council of Ten Scales governs Draknaar, with a High Sovereign selected through divine trials that test judgment, courage, arcane understanding, sacrifice, and bloodline stewardship. Metallic Houses traditionally oversee divine law, arcana, diplomacy, healing, and historical memory. Chromatic Houses traditionally command warfare, ambush, frontier defense, assassination, survival, and destructive force. Beneath the Council are temple hierarchies, ancestral shrines, military orders, bloodline monasteries, arcane colleges, and local hearth-priests. The Scale-Spire Cathedral in Cleth-Aurix's territory safeguards Ignisvorn's heart-scale. Every major rite invokes at least three Progenitors, because the faith teaches that no single bloodline can interpret the slain sun alone.

The Covenant of the Ember-Sould is woven into the laws, bloodlines, military orders, priesthoods, and daily rituals of the Draknaar Theocracy. Dragonborn are taught that ancestry is both privilege and obligation, with each Sacred House claiming one Progenitor's virtues while suppressing their excesses. Cleth-Aurix's priests administer law and orthodoxy, Charirix's followers arm the realm, Ayrthiarch's disciples train spellblades and monks, Saurivnos's agents patrol wild borders, Vurnthrik's servants conduct covert punishments, and Austra-Cleth's scholars maintain arcane towers and relic-forges. Ouss-Sphaer shelters the poor and wounded, Naminsiyesh guides arcane colleges, Sarkesh preserves history and diplomacy, and Scyllagix attracts rebels, raiders, and those who reject the Council of Ten Scales. Mortal engagement is constant: deities answer through dreams, omens, sudden changes in flame, ancestral apparitions, and divine trials, but rarely through unquestionable commands. Every dragonborn must eventually decide whether their bloodline is a destiny, a burden, a weapon, or a choice.

The Ember-Vault is the afterlife imagined by the Covenant of the Ember-Sould. Souls arrive as sparks within a vast, darkened sun. Cleth-Aurix weighs them beneath his golden scales, while Naminsiyesh reveals the memories they concealed. The worthy are carried by Ouss-Sphaer into radiant ancestral halls, where Ignisvorn's surviving spirit burns beyond reach. Those who betrayed their bloodline are claimed by Vurnthrik, who sends them into the Ashen Deep. Saurivnos, Sarkesh, and Scyllagix contest the fate of the dishonored, while Charirix and Ayrthiarch argue whether valor or victory defines a worthy soul. Austra-Cleth alone records every judgment, and none may alter the ledger once Sarkesh seals it.
