My name is Juan Rodriguez. And I am the greatest Dungeon Master alive. To the outside world, I'm an ordinary substitute teacher. But secretly, with the help of my friends on Discord, I run games and find other nerds like me. But I became lost in time. It took everything in my friends' power to clear my dungeons, and in doing so, their world was opened up to new threats. And I'm the only one dastardly enough to stop them. I am the Dungeon Master.
