Gahkthun of the Golden Lightning is an adventure visual novel that focuses on complex political intrigue and the development of technological progress. Here the world followed an alternative history, emphasizing the development of machinery and the veneration of scientists and other educated elites. But, unfortunately, even this will not save the world from wars.

The action takes place in an alternative 1908. Humanity uses steam mechanisms to maximum power, which is why almost every house has some strange outlandish mechanism with a huge number of gears. But technological progress also has a dark side. The sea has turned black due to human activity, ceasing to be beautifully blue. Many people believe that the Academy is to blame for everything. This is a special city, located on an artificial island, where prestigious or incredibly smart students study. They study many subjects, but they themselves do not understand what secrets their institution hides. Its underground passages contain many interesting details that ordinary students are not supposed to know about.

The quiet life of the world of Gahkthun of the Golden Lightning ended as soon as one of the students, Nikola Tesla, announced his intention to start a war against the ruling council. All this time, he gathered like-minded people around him to create a kind of army. It is up to the user to decide whether to join it or take the side of the law.
