Our current DnD campaign has been going on for just a bit over 5 years now. There has been several occasions when it was already supposed to end. Yet here we are, still playing the same campaign.
This time it's different. We are actually going ro get a closure for the story and move on to the next campaign soon. The last session was supposed to be already this week, but we didn't manage to complete the final battle in time so we still need to continue that for yet another session. That should be the real end.
...or at least the end of our adventure. Our GM has planned one more session after that to have a recap of our adventure and give us an epilogue for the story. What things we missed, what could have happened, and most importantly what will happen after our final battle and the end of our adventure.
It will not be only the ending for these 5 years, but also function as a bridge to our next campaign he has been planning. Set 200 years after the events of the current campaign where our actions might have some long lasting effects that have changed the fate of the world during those centuries.
