The Mer of the Late Merethic Era share distant Aldmeri ancestry, but that common origin does not produce political unity. Altmer, Ayleids, Bosmer, Chimer, Dwemer, Falmer, Orsimer, and Maormer now possess distinct religions, languages, governments, and ideas about what it means to be Mer. Their relationships range from trade and intermarriage to open warfare, theological hostility, and competition over claims to the Aldmeri past.
Most Mer recognize that the others are related peoples. The argument is over what that relationship means.
The strongest cultural connection among the Mer is their shared inheritance from the Aldmer. Related languages, ancestral gods, magical traditions, architecture, and family customs preserve evidence of this origin even where cultures have diverged sharply.
The Altmer generally claim that Summerset preserves the closest continuation of Aldmeri civilization. Other Mer frequently reject the implication that this gives the Altmer cultural or religious authority over them. The Ayleids developed powerful mainland kingdoms, the Bosmer adapted to the Green Pact, the Chimer deliberately rejected Summerset's religious order, and the Maormer maintain their own competing account of Aldmeri legitimacy.
Shared ancestry therefore creates as many arguments as alliances.
Relations between Altmer and Ayleids combine familiarity with rivalry. Both possess sophisticated magical traditions and preserve recognizable Aldmeri customs, but the Ayleids have developed politically independent city-states in the Heartland and no longer depend upon Summerset for legitimacy.
Altmer may regard Ayleid culture as an increasingly divergent branch of Aldmeri civilization. Ayleid rulers may respect Summerset's antiquity while considering White-Gold, their cities, and their celestial magic evidence that mainland Mer can equal or surpass the achievements of the Isles.
Trade, scholarship, marriage, and diplomacy continue despite this competition.
The Bosmer retain recognizable Aldmeri religious traditions, especially through Y'ffre, but Valenwood has shaped them into a society very different from Summerset.
Altmeri observers may see Bosmeri decentralization and the Green Pact as departures from refined Aldmeri civilization. Bosmer may regard Altmeri hierarchy and concern with lineage as unnecessarily restrictive.
The relationship is usually less hostile than the Altmeri disputes with the Chimer or Maormer. Trade between Summerset and Valenwood remains valuable, and their shared religious ancestry provides considerable common ground.
Relations between Altmer and Chimer are dominated by religion.
The followers of Veloth rejected the established Aldmeri order and embraced Azura, Boethiah, and Mephala as spiritual teachers. From an orthodox Altmeri perspective, the Velothi exodus represents a serious rejection of ancestral tradition. Chimer traditions instead portray the departure as a necessary escape from stagnation and false authority.
The dispute is therefore deeper than ordinary political rivalry. Both peoples understand the disagreement as a competing interpretation of their shared ancestral past.
The relationship between the Chimer and Dwemer is one of the defining tensions of Resdayn.
Chimer society is centered on ancestors, prophecy, Daedric teachings, and sacred obligation. Dwemer thinkers question divine authority and approach reality through mathematics, engineering, experimentation, and tonal principles. Each culture therefore challenges assumptions the other considers fundamental.
Despite this philosophical hostility, they are not constantly at war. Trade, territorial agreements, common threats, negotiations, and local alliances exist alongside religious disputes and competition for land and resources.
Their relationship remains unstable rather than inevitably hostile.
The Falmer preserve strong connections to older Aldmeri religion, particularly through their devotion to Auri-El. This gives them religious similarities with the Altmer even though centuries of geographic separation have produced a distinct northern society.
Relations with the Dwemer are more practical. Falmer and Dwemer communities may trade surface goods, food, metals, tools, and magical materials while also competing for mountain territory and subterranean resources.
The growing Atmoran presence in the north may also encourage Falmer rulers to seek cooperation with neighboring Mer who would otherwise remain rivals.
The Orsimer occupy an uncomfortable place within Merish relations.
Most other Mer recognize their connection to the Aldmeri past, but many also regard them as transformed or corrupted descendants of Trinimac's followers. Altmeri and Chimeric traditions both preserve stories surrounding the transformation, though they interpret its meaning very differently.
Orsimer communities often respond to this prejudice by placing greater importance on clan loyalty and independence. Relations with other Mer are therefore highly local. An Orcish clan may fight Falmer over a mountain pass, trade with a Direnni settlement, and serve as mercenaries for an Ayleid ruler within the same generation.
The conflict between the Maormer and Altmer is among the most persistent rivalries of the Merethic world.
Both claim ancient Aldmeri ancestry, but their traditions disagree over legitimacy, exile, and inheritance. The rivalry is strengthened by competition for control of southern waters and approaches to Summerset.
Unlike many internal Merish disputes, this conflict regularly becomes naval warfare. Maormer fleets, sea magic, and serpent traditions make Pyandonea a serious threat rather than a distant nuisance.
Their hostility should not imply that Maormer treat every other Mer as enemies. Their strongest political and historical rivalry is specifically with Summerset.
Religion is one of the clearest divisions among the Mer.
Altmer and Falmer retain strong forms of ancestral Aedric religion. Bosmer center their society on Y'ffre and the Green Pact. Chimer accept Daedric Princes as teachers. Ayleid city-states range between Aedric and Daedric traditions. Orsimer communities largely follow Malacath, while Dwemer philosophy challenges the assumption that powerful supernatural beings deserve worship at all.
These differences influence diplomacy as much as theology.
Two rulers of different peoples may find common religious ground, while members of the same Merish culture may become enemies over incompatible cults.
Religious and political hostility does not prevent exchange.
Merish merchants carry metals, crystals, enchanted goods, textiles, food, livestock, books, religious objects, and luxury goods between regions. Scholars exchange astronomical observations and magical theory. Craftsmen adopt foreign techniques, while sailors spread language and stories between distant ports.
Border regions are particularly mixed. A merchant settlement may contain several Merish languages, competing temples, foreign craftsmen, and families whose ancestry crosses cultural boundaries.
The differences between the Mer are therefore substantial but never absolute.
During the Late Merethic Era, no single Merish civilization dominates all the others. Summerset possesses immense prestige, the Ayleids control much of the Heartland, the Falmer remain strong in the north, and Chimer and Dwemer powers compete throughout Resdayn. Bosmer clans control Valenwood, Maormer fleets challenge the southern seas, and Orsimer strongholds survive between larger powers.
