Can you mail money across factions

In the world of Westeros, the Seven Kingdoms are divided into various factions, each with their own rulers, armies, and economies. While it's not explicitly stated in the books or show whether it's possible to mail money across factions, I can provide some context and insights.

In the world of Westeros, the concept of mail or postal services is not well-developed. Communication and trade are often facilitated through personal networks, messengers, and merchant caravans. The Iron Throne, the ruling power of the Seven Kingdoms, does have a network of messengers and couriers, but it's not a formal postal service.

Given the medieval-like setting of Westeros, it's unlikely that a formal postal service would exist, let alone one that could facilitate the transfer of money across factions. The factions themselves might have their own internal systems for transferring wealth, such as gold, silver, or other commodities, but these would likely be limited to their own territories or alliances.

In the show, we see instances of characters sending messages, goods, and even people across the realm, but these are often facilitated through personal connections, trade agreements, or military conquest. The idea of mailing money across factions is not explicitly explored, and it's unlikely that such a system would be in place.

However, if we were to imagine a scenario where a formal postal service did exist in Westeros, it's possible that factions might establish their own postal networks or agreements to facilitate the transfer of money and goods. This could be done through a combination of secure messengers, encrypted messages, and trusted intermediaries.

In the world of fantasy, where magic and technology can be used to facilitate communication and commerce, it's possible to imagine more advanced postal systems that could transfer money across factions. However, in the context of the Game of Thrones universe, it's unlikely that such a system would be in place.
