House Rank Structure

House Lord and House Lady - Whichever one has bonded with the Element of Harmony usually is the one more in control and make decisions during the House meetings with the other House Lords and Ladys.

House Heir - The child of the House Lord and Lady, chosen to take on the element of their house, though it isn't always the eldest child despite that being the common choice. Depending on the previous Element Holder, they may not bequeath the element to the heir before their death, though most do so they can teach them how to harness the power.

House Nobles - Various ponies, many of whom have some sort of relation to the House line, they are usually bequeathed responsibilities for certain aspects of running the House domain.

House Officials - Those not related to the blood lines of the Houses, but still of importance, nominated their positions instead of being born into them.

House Compassion

Sun Shire, home to the House of Compassion and the heir of House Compassion and Chroma's cousin, Fluttershy Soleil, and her guard. House Compassion is one of the only two Houses to have only ever consisted of a single pony tribe, along with the House of Loyalty, both of whom have only ever had Pegasi. Throughout history, they have dwelled in Sun Shire, the city in the clouds that handles much of the agriculture-related duties of pegasi while also handling the creation of rainbows and other weather-related duties.

House Loyalty

Stormholm, home to the House of Loyalty and Lady Knight Chromatic Dash, Heir to House Loyalty.The House of Loyalty has always been one of the most militant of the Houses, known for their shining knights, flying through the sky in their armor made from Mithril forged by their allies from the Griffin Empire using ore mined in the mines of the House of Merriment. The Knights of Loyalty have long soared across Equestria, protecting the innocent as they travel the paths to trade and travel, the Elemental heirs often becoming the Knight Commanders of their pegasi armies, the House eventually becoming close to House Compassion, the latter giving control of their forces to the former.

House Arcana

Ether Peak, home to the House of Arcana . House Arcana has two heirs, but the chosen heir is Twilight Sparkle. For a long time House Arcana shared its home with House Generosity in Canterlot, but eventually they left to find a home of their home, mostly unicorns but also pegasi and earths. Eventually, they found a natural nexus of arcane energies at the top of what they would eventually call their home, the arcane city of Ether Peak. From this city, their knowledge of the arcane has become grown rapidly, learning how to do feats of magic that would be impossible elsewhere, literally, the magic of the place fueling those who dwell their, even non-unicorns benefit from it, the creativity and natural skills fueled making it a hub for tradesponies, crafting masterful works and sending them out across the world.

House Generosity

Canterlot, home to the House of Generosity with Lady Rarity, truly the most regal of the Elemental Heirs. The city of Canterlot was originally the great home to the Houses Magic and Generosity both, but the people of House Magic eventually left to find their own home, a decision that House Generosity understood, and since the city has thrived. Though Ether Peak quickly became a center for innovation, magical advancement, and trade, Canterlot remained the peak of cultural influence in the entire kingdom, as well as the biggest source of crystal trade the world over, especially with the rise of the Diamond Dogs Underpire, filling the House's coffers to overflowing, able to buy the things they need to sustain themselves and live a life of relative luxury, making most believe that the people of Canterlot are all soft and weak... however, the soldiers of the Canterlot Guard are some of the toughest and strongest in the kingdom.

House Honesty

Cookie's Rest, home to the House of Honesty . House Honesty's heir, Lady Applejack, though she's far from ladylike. House Honesty found its home in the ancient, but sturdy and simple castle of Cookie's Keep, eventually a town sprouting nearby called Ponyville, founded by the Apple family. Over time, the Apples became part of the family line of Honesty, the land becoming fertile, able to produce more food than they needed, so they soon became a center for agricultural trade, much of what they produce going to Stone City and Ether Peak due to their inability to produce food on their own due to their geographic locations.

House Merriment

Stone City III, home to the House of Merriment. Lady Pinkamena of House Merriment is... rather odd, but a great friend to all. House Merriment has always been a rather... odd line. Despite the name, many of the bloodline have been rather mirthless and serious, unsurprising given their rather grim history. The soldiers of the House, known as the Merrymen, are far from what their name implies. They're not as well trained as the Canterlot Guard, or as well disciplined as the Sky Knights... but they are experienced in battle, more so than any other unit, and they have more troops than any of the others. The Merrymen have been the front line defense in the war against the Underpire, and has suffered the most loses due to their House being built around mining, rock farming, and crystal farming, of course making many enemies. They have been driven from their city in crushing defeats twice before, always waiting until the last moment in their stubborness to retreat.
