Game description from the publisher:
In Once Upon a Time, players tell a story together using cards that show fairytale elements and endings. Now add more adventure to your game with the Once Upon a Time: Seafaring Tales expansion. Inspired by daring pirates and stories of the sea, the 38 Story Cards and 17 Ending Cards in this set can be shuffled into your Once Upon a Time storytelling card game deck to add new themes and more variety to your game. For an even stronger nautical feel, try removing some of the core Story or Ending Cards.
