Following the sale of its underperforming colony of Vasaon to Britain in 1708, the Polish-Swedish Union exited the New World, leaving the field to powers with stronger navies. Britain immediately capitalized on this consolidation, securing its home front through the Union of Kingdoms Act in 1705, which united England, Scotland, and Ireland into a single realm. The Dutch turned their attention to the interior of the continent, exploring the massive "Groot River" system in 1653 and discovering the native trade hub of Coopstad. Their expeditions mapped a transition from fertile riverlands to arid deserts in the west, ending at the impassable "Snewbergen" mountains. Beyond these peaks, they discovered a mysterious rainforest region inhabited by aggressive natives and extinct megafauna, claiming the vast basin as the "Groot Territory" in 1690.

Britain expanded its colonial footprint along the eastern seaboard, establishing a distinct economic divide between the industrializing northern colonies like New Lancaster and the plantation-based southern colonies like Philippia. This expansion faced a challenge from unauthorized Irish Catholic settlements along "Patrick's River." In 1732, the British military intervened to assert control, besieging and destroying the Irish capital of New Dublin before reorganizing the territory as "New Britain." However, British attempts to push further west were halted by the "Green Confederacy," a powerful alliance of centralized native states in the Green River Valley. After suffering a catastrophic defeat at the Battle of Cotter in 1768, where native cavalry destroyed a British army, the Crown abandoned plans for conquest in the region. Whilst Mornaea proved troubling in some instances for the British Empire, in El-Rabeeah, its fortunes shifted. Due to Madjriti neglect and the chaos of the Grand European War, Britain was able to secure a foothold in the southern reaches of the continent, much to Madjrit’s chagrin.

On the western coast, the Ming colony of Hoshih grew rapidly after the Emperor incentivized settlement in 1680. In 1718, Chinese explorers discovered that their colony was actually a massive island separated from the mainland by an inland sea, a geographic quirk that had preserved unique wildlife like dwarf mammoths. To secure this strategic asset before Europeans could discover it, the Ming court launched a massive resettlement program. Meanwhile, in India, a war broke out between the Dutch and Madjriti in 1715 over control of the subcontinent's trade. The conflict weakened both powers, allowing the British English Indies Company (EIC) to capitalize on the situation; in 1735, the EIC secured the wealthy province of Bengal from the declining Turani Empire, establishing a dominant foothold in South Asia.

British imperialism faced mixed results elsewhere. In Southeast Asia, the EIC aggressively established monopolies and protectorates, engaging in a diplomatic struggle with the Ming Empire for influence. In East Africa, however, a British invasion of the Swahili City-States in 1702 ended in disaster, with the EIC fleet destroyed and the army routed, forcing a retreat to the Kingdom of Sion. The British found more success in Central Africa, bombarding the Kingdom of Kongo into submission in 1722. This expansion provoked tensions with Madjrit, leading to naval skirmishes in the Atlantic. To prevent a full-scale war, the two powers signed the Treaty of Bath in 1749, dividing African spheres of influence at the equator. France, recovering from domestic turmoil, established a colony in South Africa in 1695 to secure a route to its Asian possessions.

The Sultanate of Madjrit established a distinct colonial society in El-Rabeeah, defined by the mass conversion of indigenous populations to Islam and the extraction of immense wealth through gold, silver, and sugar. To fuel this economy, the Sultanate leveraged its control over West African ports to import vast numbers of slaves, many of whom eventually gained freedom through conversion and intermarried with the colonizers. This process created a racially diverse, heterogeneous society that lacked the strict segregation seen elsewhere. However, the influx of colonial treasure ultimately destabilized the metropole; relying heavily on this extraction to fund a massive military, the Madjriti court neglected domestic industry and infrastructure, leading to a cycle of debt and inflation that rendered the empire’s economy fragile despite its superficial riches.

France, facing similar financial perils, adopted a more regimented approach to its colonies in Ecab and the Caribbean. While the French Crown successfully spurred domestic manufacturing to offset its debts, it relied heavily on the output of sugar plantations and silver mines. To solve its labor crisis without trading with the rival Madjriti, France established a controversial slave trade with Eastern Rome to procure Muslim captives and later secured direct access to African labor through its South African colony. This resulted in the imposition of a rigid racial caste system in New France, stratifying society from European-born elites down to "Mohammediens," a permanent underclass of slaves subjected to the harshest treatment and denied any avenue for manumission.

The Dutch and British empires developed dual economic structures that separated their vast, resource-rich mainland territories from their lucrative island plantations. The Dutch focused on extracting furs and timber from the sparsely populated Groot Territory while generating massive profits from sugar produced by slaves purchased from Madjrit in the Caribbean. Britain similarly divided its Mornaean holdings between an industrializing north and a plantation-based south, but unlike the Dutch, it encouraged large-scale settlement to create a society that mirrored the British Isles. Britain sustained its labor needs through illicit trade and the importation of African Christians, while the small Danish colony in the region inadvertently became a refuge for escaped slaves fleeing the brutal regimes of the major powers.
