My first exposure to Thay was in the figure of Edwin, an arrogant character in the Baldur's Gate video game series. He was very far from his homeland, but he brought a distinctive accent and attitude with him. Edwin's portrait was serious, his lines were sarcastic and amusing, and he was the best damned arcane caster in the game. He made such a first impression that I quickly thought of Thay when the time came to run my first evil campaign.
When I turned to the published materials, though, I couldn't find enough to satisfy my curiosity. For such a large and populous country, Thay seemed wide open for more development and personalization. I didn't just want the player characters to visit; I wanted them to live there. So I began the process of making my own version of it.
I want to encourage others to give Thay a chance as the setting for a whole campaign, and not just a one-shot raid into bad-guy territory. I also want to share the things I've created for Thay, in the hopes that someone else will be able to benefit from it. I don't follow the canon and have no plans to. Instead, I aim to develop unique details on the regions and peoples of Thay and provide a look at my own long-running Thayan campaign.
