It's a leftover from earlier times, before Aegon's Conquest.
Most importantly, let's start with that name, 'The Seven Kingdoms.' It's wrong. But where is the Eyrie as opposed to the Twins as opposed to Highgarden? How far is King's Landing from Winterfell? The Wall is in the North, of course, and Essos is across the Narrow Sea. But even with the opening credits swinging around from city to city, it can be hard to remember where exactly everything is located. The title sequence's map of significant locations (which changes each season) helps remind viewers where the action is based. Game of Thrones' iconic opening sequence is an excellent tool to help you get a lay of the land. With so many possibilities, fans should refresh their memories of what the seven kingdoms are in Game of Thrones and how the continent is laid out. Everything from an adaptation of Dunk & Egg to a series about Robert's Rebellion could head to HBO and HBO Max. Since HBO announced the Thrones prequel spinoff House of the Dragon, there have been hints of more Westeros-based series in development as well. The Game of Thrones series may have come to an end, but the franchise has only just begun.
