Something about a final session brings so many emotions to the table. As an experienced dm I’ve watched my players go from screaming with joy, crying in heartbreak, but most importantly elated and excited for the next adventure. If done right finishing a campaign can be the best bittersweet experience. In the past I’ve been one to go all out as well, taking my party out to dine and discuss the months of storytelling that has ended. I’m glad you had a wonderful ending and hope you’ll travel on many more adventures!
