Aetherra

This world exists in a late medieval high-fantasy era, comparable to the standard technological level of most Dungeons & Dragons settings: fortified cities, feudal territories, knightly orders, arcane towers, monasteries, and merchant leagues. Steel weapons, chainmail, siege engines, and long-distance caravans define civilization. Decades ago, a cataclysmic arcane event known simply as The Emergence reshaped reality. Across the world, Dungeons manifested spontaneously, along with planar rifts and arcane distortions. At the same time, an unseen metaphysical force — referred to as the System — began marking certain individuals. Those chosen by the System awakened measurable growth in power: Structured advancement of abilities Defined archetypal paths (similar to character classes) Observable improvement through combat and dungeon delving Scholars debate whether the System is a remnant of a lost Netherese-style magical experiment, a sentient arcane lattice woven through the Weave itself, or a planar anomaly. Whatever its origin, the old feudal kingdoms collapsed under the strain of monsters, planar incursions, and empowered individuals. In their place rose Guild Confederations, which now function as the primary governing bodies of the world. The most influential organization is the Adventurers’ Consortium, where individuals formally register, accept contracts, and rise in rank through documented achievements. Separate major guild structures include: The Adventurers’ Consortium The Mercantile League The Arcanists’ Circle (arcane research & magical study) The Whisper Network (intelligence and information control) Independent companies and sworn adventuring bands (equivalent to player parties) may also form registered Companies or Free Blades under guild recognition. The System: The System functions as a narrative-compatible leveling framework inside the world: Individuals “Marked by the System” advance similarly to player characters. Advancement is triggered by overcoming meaningful threats. Certain abilities manifest as structured class features. Multiclassing is interpreted as cross-disciplinary awakening. NPC commoners generally do not possess System marks and advance slowly, if at all. Guild ranks loosely correspond to Tier of Play in D&D: F Rank → Levels 1–2 E Rank → Levels 3–4 D Rank → Levels 5–6 C Rank → Levels 7–8 B Rank → Levels 9–10 A Rank → Levels 11–12 S Rank → Levels 13–16 SS Rank → Levels 17–20 SS-Rank individuals are considered world-shaping forces.

Nine major continents dominate the world: Grad Hizu Frontum Odenwald Drunken Syndren Olgen Polk Ungan The former political borders no longer function. Instead, territory is controlled by guild alliances, powerful adventuring companies, mage enclaves, or dominant racial factions.

The world includes the core D&D ancestries: Humans Elves (high, wood, and drow enclaves) Dwarves Halflings Dragonborn Tieflings Gnomes Half-orcs Vampiric bloodlines (treated as lineages or cursed states) Undead-afflicted peoples

Cultural tension is high. With no unified crown or empire, resource wars, magical territory disputes, and dungeon-claim conflicts are common. Some dwarven holds have become dungeon-clearing strongholds. Certain elven realms have sealed their forests against planar corruption. Human city-states rely heavily on guild protection.

Magic exists in three principal forms: Arcane Magic Drawn from the Weave or equivalent arcane substrate. Practiced by Wizards, Sorcerers, Warlocks (patrons are powerful extraplanar entities, not gods), and certain Fighters or Rogues with arcane archetypes. Primal Magic Derived from nature, spirits, and the raw life force of the world. Practiced by Druids and Rangers. Inner Discipline Ki, psionics, or awakened internal energy. Practiced by Monks and certain rare disciplines. There are no active gods influencing the world. Clerics and Paladins instead draw power from: Sacred Oaths Cosmic Principles Abstract Ideals (Justice, Conquest, Knowledge, Mercy) Ancient planar forces Religions exist culturally but do not grant direct divine intervention.

Dungeons function as unstable planar anchors. Some connect to: The Shadowfell The Feywild Elemental planes Aberrant Far Realm-like spaces Creatures emerging from these rifts include: Aberrations Fiends (not divine agents, but planar predators) Elementals Construct remnants of lost civilizations Draconic broods Not all planar entities are hostile. Some bargain. Others study mortals. Many are inscrutable.

Age of Nomads Age of Kingdoms Age of Steel & Crowns (standard medieval era) The Emergence (arrival of Dungeons and the System) The Guild Age (current era) The Emergence shattered monarchies and redistributed power to individuals strong enough to claim it.

Currency: Crown Additionally, high-value trade includes: Monster cores Spell scrolls Enchanted weapons Alchemical reagents Dungeon relics Caravan routes are heavily guarded. Sea trade remains dangerous due to planar distortions and sea-born aberrations.

There is no global legal structure. Each territory is governed by: A guild charter A dominant adventuring company A mage council Or a militarized racial enclave The Adventurers’ Consortium provides neutral arbitration between major factions. Adventurers are respected but feared. They are both protectors and potential tyrants. Formal Adventurer Academies train initiates in: Combat tactics Dungeon survival Magical literacy Monster ecology

Dungeons contain a vast range of threats: Undead legions Ogres and giants Dragons Hags and witches Mimics and living constructs Aberrant horrors Cursed knights Arcane war machines Some Dungeons evolve over time. Some appear sentient. A few have never been cleared — only survived.
