My friends and I will be celebrating our 25th anniversary as a D&D group next year. We've played every edition (except 1st) and we're really enjoying 5e. Even though we're currently running Waterdeep: Dragon Heist right now, we're getting really close to the end. What would you recommend as a one-shot (preferably 1st-level) adventure to celebrate a quarter century of playing as a group? I have the Starter Set already, along with Tales of the Yawning Portal and we've run most of those early adventures when they were originally released. Perhaps something you'd recommend from the DM's Guild?
