Gwent: Black Sun is a fantasy tactical card role-playing game. Some say that the end of the world will be in ice, others that fire will scorch everything. Others heed old prophecies, predicting that darkness will be the end of all things. Once every century, the sunlight fades as shadows grow and invade the world of the living. Corrupts, distorts, drives you crazy. However, in a world full of curses and disasters, there are untouched places untouched by evil and heroes who make their way through the darkness.
