Conquered by Twilight, the Kingdom of Hyrule struggles to resist its dark and monstrous oppressors.
Type: BlossomThree main factions are at play in Hyrule.
KINGDOM LOYALISTS
The displaced and frightened people loyal to the royal family of Hyrule make up one part. They support Zelda, even if the situation looks pretty dismal, and have hope that someone will save them from this pickle the kingdom's found itself in. They wait on the prophetic Hero, chosen by the goddesses themselves.
Most of these loyalists are Hylian in race, but there are others represented as well, including the mountain-dwelling Goron and aquatic Zora. There is little they can do individually to challenge Zant, especially for those fearing retribution, but they do what they can.
DARK INTERLOPERS
In the other corner of the ring are the Twilight invaders, led by the Twilight King Zant and, secretly, the Gerudo Prince of Darkness, Gannondorf. The people of the Twilight Realm are twisted by Zant's ambitions, driven to the conquest of the Hyrule they had been exiled from since time out of mind. They are led by Zant. Zant, in turn, is secretly led by the Prince of Darkness, Gannondorf, the Gerudo prince and bearer of the Triforce of Power... but power unchecked is dangerous in its ambitions.
Zant's Twilight beasts and minions do his dirty work for him. Other denizens of darkness support them, including creatures under Gannondorf's influence, such as lizard-men and monstrous beasts. They're often cunning but dumb as a bag of rocks, and fiendishly strong.
NEUTRAL PARTIES
Some have opted for a more neutral solution, choosing to weather out the storm of civil war. They flock either to distant places in the World Tree or the fringes of the kingdom, trying their best to avoid conflict. These include all races and forms of life -- even some disillusioned monsters or Hyruleans. Their motivations are as varied as the worlds that lie beyond Hyrule, and not all of them default to being friendly towards outsiders.
The level of technology in Hyrule is mostly mediaeval. Soldiers rely on melee weapons like halberds and swords as well as steel armour, and archers make use of composite bows made of wood, horn, and laminate. Some materials are magical in nature, defying 'mundane' physics, such as enchantments laid on items to strengthen them beyond mundane durability.
Examples of more modern technology native to Hyrule can be found in some places, such as telescopes and lenses. Such things are rare, though, requiring expertise to make and often made at great cost. Other materials that should be rare and costly may not necessarily be, such as glass making use of magic to ease the smelting process. As a result, glass windows are relatively commonplace. Hygiene is also very good, with even some of the poorer homes boasting private baths.
Technology has also filtered in through the breach, brought by those from the World Tree. More modern examples like cell phones can be found, though mostly in the hands of eccentric collectors and the very wealthy; information technology has no native infrastructure in Hyrule, so it doesn't always work at its best. The people of Hyrule are slow to trust such marvelous wonders, suspicious in the wake of their conquest by the Twilight.
There is some trade with other worlds, but many of Hyrule's merchants don't know how to value such strange foreign goods. As a result, trading is a little bit tentative, but it does happen.
