I'm always banging on about how Arthur and Charles are two sides of the same coin, how they complement and slot into one another, but honestly I think that's true of the other members of the UK as well. Putting aside their modern roles of how they work alongside their respective governing structures, they’ve all played their part in the making and maintenance of Britain, and the empire. They were in it together (however begrudgingly) and none were excluded (or inculpable).
I'm including the Republic of Ireland in this as well, because it played a part for a long time, and I've found myself thinking about Ireland as a personification a lot lately. This is not to pigeonhole them, as ultimately this is only a small part of their individual characters—and they all have ways of bleeding into one another, as these are facets that exist within all of them—it’s simply because I enjoy the idea that, taken together, they each embody the major components or occupational spheres that are often identified as Britain’s historical sources of strength:
Arthur [England / United Kingdom]
Arthur oversees. His long lasting occupations include aristocratic landowner, diplomat, senior advisor of the central government, and high-ranking naval and air force commander, alongside broader military leadership and colonial/exploration-linked roles. This represents him as a figure who holds the inherited structure of the state and projects it outward to the wider world, playing a large role in coordinating continuity and relations.
Charles supervises. His career revolves around law, business, finance, civil service, bureaucracy, and governance. This represents him as the internal operating system of the United Kingdom’s institutions. He structures rules, manages capital flow, works closely with the treasury, and maintains administrative order within the dense institutional core of the state.
Duncan innovates. His primary occupations are that of a scientist, inventor, and researcher, developing practical inventions and systems used across civil and military contexts. Duncan’s own military experience evolved from clan warfare and Jacobite service into British Army regiments like The Black Watch, later moving into the technical corps as scientific and technological developments transformed warfare and defence. He’s also focused on energy research and, more recently, environmental science.
Taliesin preserves. His most lasting careers are as medical practitioner (including service in the military medical corps as a physician and combat medic), conservation worker, and bardic/cultural worker (poet, performer, and preserver of language, story, and cultural memory). This represents him as the care and continuity function of the UK, dedicated to physical wellbeing, stewardship, and cultural preservation.
Victoria [Northern Ireland] - belonging to @inionnarequiem
Victoria maintains. Her primary occupations are those of the artisan, fabricator, and mechanic, particularly in naval shipbuilding and military engineering. She is the productive and material face of the United Kingdom: the capacity to make the abstract tangible. She represents a resilient endurance that persists through divided identity, traditions, and loyalties.
Ruadhán [Republic of Ireland]
Ruadhán sustains. His careers have included religious vocation, infantry soldier, farmer & manual labourer, smith, and publican. This represents him as deeply defined by lived physical work, where community life is anchored in shared informal spaces, and culture is preserved through everyday social gatherings. His infantry service reflects Ireland’s historical role as the disproportionate pillar of enlisted frontline manpower within British military structures.
Arthur could not govern without Charles. Charles could not fund anything without Victoria. Victoria could not build anything without Duncan. Duncan could not innovate without the social care, agricultural foundations and manpower provided by Taliesin and Ruadhán, and none function together smoothly without Arthur’s coordination.
And what I particularly like is that nobody's role is actually "less important," yet it clearly speaks of how power structures function. All of these roles are indispensable, but they’re not rewarded equally. The people who direct the system occupy the top of the hierarchy while the people who sustain it are expected to remain in lower tier positions within society, and that tension, I think, is very British.
