Refers to a species that is naturally born from its parents or crafted by the hand of a god, possessing a limited lifespan. This limit can be extended through the mastery of the art of Dahäl or divine intervention, which may even abolish it altogether.
Originally, no mortal was capable of wielding Dahäl. Mastery of it only became possible when the first mortal hero proficient in Dahäl (Amarianne) was created by the god of Tellurön (Gaya).

A variation of the mortal species: born from two Eternän parents or crafted by the hand of a god. Their lifespan is unlimited, provided they are not affected by forces beyond their will and resilience (murder, disease, suicide, etc.). The term often refers to immortal humans but actually encompasses any material being with a soul.
Eternäns possess an innate mastery of Dahäl. They are unaffected by the passage of time, but they can experience fatigue. After several millennia of being « awake, » it is common for them to enter periods of slumber lasting several centuries. These periods can consist of repeated months-long sleeps until their mental fatigue dissipates completely. The longest recorded slumber lasted 76 cycles for an original Eternän who had not rested even after hundreds of thousands of cycles.

Special Cases:

• Demigods are considered Eternäns, though they are not necessarily born of Eternän parents. Their status is always a gift from a god and is often accompanied by a unique ability (strength, ubiquity, telepathy, etc.).
• Heroes, unless born Eternän, are not immortal. However, they possess a unique gift that they can use without practicing Dahäl.

A variation of the mortal species: born of one mortal parent and one Eternän or Anteterän parent. Their lifespan is greatly extended compared to mortals but remains finite. They do not possess an innate mastery of Dahäl like mortals.

Distinct from the first three species, Sources can only be created by a god’s hand. Additionally, they cannot truly die but can be partially or fully absorbed by a living being or a god. They are the origin of the force known as Dahäl.

Gods are everything and nothing simultaneously—everywhere and nowhere. However, they can assume a form to interact with living beings. Their abilities are limited to the dimension they created (as each of the seven gods once created their own dimension, or realm). Their influence on other worlds is minimal unless they ally with other gods to gain access to their domains.
Gods are not born; they self-generate. A god cannot die by any means involving an element of a dimension. Only beings originating from the void (i.e., the gods themselves) can end the existence of another god.
A god possesses a soul and personality, as they set an objective for themselves at the moment of their first appearance.
Creating specific species within their dimension requires immense power and will, which is why Eternäns, Anteteräns, and Sources are rare across all dimensions. Only Môt (Alpha) and Irilion were able to create an unlimited number of Eternäns before the creation of a magical Source disrupted the balance that allowed this exception.

Each realm has its own calendar.

• In Tellurön, the term « year » refers to a complete orbit of Earth around the sun, equivalent to 365.25 days. Since the disappearance of the Eternäns, the calendars used to mark years have changed multiple times. Notable examples include the New Calendar of Tellurön, starting at the beginning of Ranwë’s Great Crusade (-5200 years in the Christian calendar), and the Solar Calendar, which predates the New Calendar and begins with the unification of the worlds by Namrïn (-20,000 years in the Christian calendar).
• In Angband, days are marked by fluctuations in the ambient light intensity. A full cycle of this variation equals two weeks in Tellurön. The term « year » does not exist in this realm; instead, « cycle » is used, corresponding to 26 Angband days or 364 Tellurön days.

Realms are characterized by their material space and temporal continuity. They can be connected via portals that allow the transfer of matter, life, and magic between them. However, vital energy (distinct from Dahäl) can travel from one dimension to another without requiring a portal, provided the creator god of the dimension permits it.

There are other realms besides those created by the gods, but these are ephemeral. They can be created by powerful Dahäl users or through a demigod’s power but always end up consumed by the void.

Temporal distortions between worlds are virtually non-existent—or at least negligible within the explored regions and central areas of the worlds.

Each universe has multiple languages. Their evolution and number largely depend on the lifespan of the inhabitants of each dimension. For example:

• In Tellurön, where nearly all inhabitants are mortal, the number of languages is highly varied.
• In Angband, there are only a couple of languages, as the Eternäns’ continued presence slows the evolution of a common tongue, with many still practicing Finirion.
• Other realms, such as Sirius or Bilgart, have never seen their languages evolve.

All languages stem from a single root, the Language of the Gods, which is nearly impossible to trace in Tellurön due to the extent of linguistic evolution. This divine language is still mastered by Etotsira, Lether, Athena, Ulik’atar, and (before their deaths) Azazël, Relgon, Black Flame, Mélanth, Ulik’umi, and the Man of Bilgart.

The concept of life after death and the principles governing revenants (incomplete resurrections) are detailed as follows:

• Revenants transmit an invisible sadness to those around them. They are perpetually driven by suicidal impulses. For this reason, when the dead are revived long after their death, they never return in the same state as before. Their dissolution into the ether has already begun, and having experienced eternal rest, their revival induces deep depression, sometimes murderous madness followed by suicide.
• Those revived shortly after death generally remain in shock for several weeks but develop a form of schizophrenia, leading them to withdraw into themselves.

No revived individual has ever described their feelings about the afterlife. They become aggressive and violent but never answer questions on the topic, even when calm.

The Eight Errors are exceptions to these rules. They exhibit no emotions, show no violence unless someone means them harm or obstructs their will. However, should anyone oppose them, they can display extreme violence and unparalleled cruelty.
