The Crown of Aragon is not a single uniform state. It is a chain of kingdoms, counties, islands, ports and legal traditions held together by the monarch. A royal order that is routine in one realm may require negotiation, witnesses or a separate grant in another. Adventurers serving the crown therefore spend as much time proving which law applies as they do carrying out the order itself.
Alfonso V rules a Mediterranean system that stretches from the Iberian east coast to Sardinia and Sicily and, through his conquest of Naples, deep into southern Italy. The reach is impressive; the administration is deliberately uneven. Local courts, merchant communities, nobles, island councils and port officers preserve rights that cannot simply be erased by a distant signature.

The Inquisition of Flame and Iron in the Aragonese Realms
The Inquisition of Flame and Iron is a major force in the Iberian lands and cannot be dismissed as a Castilian concern. Torquemada’s agents operate through influential noble patrons, temple officials, merchants and local inquisitors in Aragon, Catalonia, Valencia and Mallorca. They investigate foreign cults, maintain lists of suspected spellcasters and press for the transfer of fugitives from Castile. Some regional authorities cooperate because the Inquisition brings money, investigators and useful intelligence; others resist its attempts to override local privileges.
In Zaragoza, powerful households argue over an inquisitor’s right to summon a noble servant. In Barcelona and Valencia, merchants can find a tribunal informer at the next warehouse, while rival magistrates fight over seized cargoes. Mallorca’s shipping lanes carry witnesses and confiscation ledgers across the sea. Aragon’s ties to Sardinia, Sicily and Naples give Torquemada further contacts, but those realms have their own courts: he must negotiate, influence or act secretly rather than proclaim Castilian law there.
The Inquisition is powerful precisely because its enemies cannot escape it merely by crossing into another crown. Yet Alfonso V’s officers are no more Torquemada’s subjects than the city councils of Valencia or Barcelona; a failed extraterritorial arrest may become a quarrel between sovereign courts.
Gods and Sacred Powers of Aragon’s Realms
The Iberian Pantheons distinguish eastern Iberian and Celtiberian deities from the maritime Punic and Roman-influenced traditions also present in these realms.
Royal rites: The Aragonese realms inherit distinct eastern Iberian and Celtiberian sacred traditions. In the inland towns, Lugus, the Matres and local protective gods are invoked by households, guilds and political patrons; Epona is honoured among horse-breeding communities. Coastal and river sanctuaries retain local divinities, some whose ancient names survive only in inscriptions. Roman-style worship of Jupiter, Juno and Minerva persists in particular older civic institutions, but it does not replace the indigenous gods as the kingdoms’ sole official pantheon.
Coast and mountains: Along the Mediterranean coasts and old trading routes, the Phoenician and Punic gods leave lasting cults of Tanit and Melqart among families of sailors and merchants. In Iberian sanctuaries, gods such as Betatun are known from ancient dedications, although their precise powers are disputed. The hills and inland horse country honour Epona and their own local guardians; Greek sea gods may be encountered in foreign merchants’ shrines rather than universally replacing those rites.
What divides worshippers: The Inquisition of Flame and Iron seeks supporters among noble families and official temples, but it cannot command every council or shrine. An examiner who confiscates a fisherman’s ancestral image of Tanit may lose the goodwill of an entire harbour—and give a rival magistrate the opportunity to protect it.
What Is Happening Right Now?
Alfonso rules from Naples
The king’s Italian court consumes attention, money and diplomatic energy. Western officials must often act in his name while waiting for instructions that have crossed the sea.
The Peace of Lodi changes Italy
The settlement among the Italian powers ends one phase of northern war, but Alfonso’s ambitions and alliances remain part of the balance. Merchants and captains now have to learn which wartime privileges survive the peace.
Each realm guards its privileges
Aragonese, Catalan, Valencian, Sardinian and Sicilian institutions do not become interchangeable because they share a king. Taxation, military service, inheritance and local office remain recurring sources of negotiation.
The sea holds the monarchy together
Couriers, grain fleets, royal galleys, merchants and private ships carry authority between shores. A lost convoy can become a constitutional problem as quickly as a commercial one.
Major Realms and Routes
- Aragon and the western court: noble and municipal privileges shape royal power inland.
- Catalan and Valencian ports: trade, shipbuilding and Mediterranean credit connect the western realms to the islands and Italy.
- Sardinia: royal officers and island communities negotiate authority across harbours, uplands and old jurisdictions.
- Sicily: Palermo, grain and the central Mediterranean make the island vital to the wider crown.
- Malta: the islands sit within the Sicilian-Aragonese political world and guard routes through the central sea.
- Naples: Alfonso’s southern Italian kingdom is joined in his person but remains politically distinct from his other crowns.
Adventure Pressure
- Two lawful orders: officials from different realms produce royal documents that contradict one another because both were issued under different legal traditions.
- The missing galley: a ship carrying tax silver and sealed appointments disappears between Sicily and Sardinia.
- A privilege older than the king: an island community produces a charter limiting a royal officer’s powers. The officer insists the document is forged.
- The Naples succession: Ferdinand of Calabria is Alfonso’s heir in Naples, but the king’s wider dominions have different succession arrangements. A document that appears to merge them would destabilise half the Mediterranean.
Historical Sources
Treccani, Alfonso V the Magnanimous provides the core chronology of Alfonso’s kingdoms and conquest of Naples. The component realms remain separate political bodies under the same monarch; campaign relationships and adventure hooks are original.
