I presented the Strangest of Sorts to my players at the start of a new Cairn campaign. My players were all new to Cairn (having previously played other games as well as 5e) and the rich backstories and neat abilities got them more excited to jump into this new game. Several sessions in I can say as a Warden that the Gremlins are a gift. Highly recommend if you're looking for pre-generated characters, or just to study an example of foreground growth.
