Longest Campaign Played.
The Temple of the Spider Queen. Most amazing story line I have ever had the pleasure of playing in. We played for nearly two years in the same campaign. My father, my sister, one cousin, while the DM was another cousin. It was a blast, over the course of the campaign I was still learning and would make many mistakes resulting in the death of 17 of my characters. Finally a Drow Druid made it to the end and managed to live.
