A Call to the Feywild is a short, but expandable encounter fit for a group of four 2nd-level characters featuring a Faerie Dragon as an unwilling switchboard operator.
It works perfectly as an introduction into the playful nature of the creatures of the Feywild, and can tie the characters to various powerful feywild creatures, such as an Archfey or Tasha/Zybilna herself. A great introduction to The Wild Beyond the Witchlight, but is also suitable as a short random encounter.
The encounter includes a new magical item: the Conch Shell of Communication. If it ends up in the hands of the players it can function as a great way to introduce additional plot hooks, or just be a fun item to play with.
