Steven Black has posted a short encounter shard at FASA. It is made for Novice level (Second to Fourth Circle). The shard was, as mentioned in the article, inspired by an article about Living Root Bridges. This is hopefully one of many shards to come.
Adventure Goal: Getting the group involved. One potential goal is that the group needs to cross either the Servos or Galanga River and hears rumors about a bridge in the area from local natives.
The full shard can be found at FASA’s Articles page.
