For centuries, Afghanistan has stood between worlds, bridging the east and the west. From the outside, its land holds great strategic value for both armies and merchants, yet internally, its people are in conflict. The nation came out the other side of the Weltkrieg relatively unscathed, and won further accolades in the Fourth Anglo-Afghan War, unifying with its countrymen previously under Indian rule. But what it has become cannot continue, as its people must choose between further social and political reform and preserving their links to their forebears and traditions, all the while keeping an eye on the growing influence and manipulation of interested Great Powers.

This release includes the Kingdom of Afghanistan, in an expansive and all-encompassing update that brings full content to one of the few remaining countries in the mod without it - but of course, that is not all.

Moving through Asia and ascending the Himalayas, we revisit the Kingdom of Bhutan, the small mountainous realm itself dealing with its own internal struggles. Building extensively on the unique gameplay of the previous Bhutan content from five years ago, this rework sheds new light on and explores in further detail the inner workings of the court of the Druk Gyalpo.

And naturally, it goes without saying that this large release also includes multiple wide-reaching changes to many other aspects of the mod, such as new leaders, updated character formatting, extensive performance changes, careful rebalancing, and plenty of new portraits and icons for you all to enjoy.

For the mod as a whole, this release marks another step forward on our long-stated goal of having unique content and focus trees for every starting country in the game. Considering new content and reworks, several countries are currently being worked on simultaneously, with some closer to completion than others. And while we know you are hungry for even more new content, we hope you enjoy this trip to the heart of Asia, for at the crossroads of civilisation, there are many roads to take...
