The Cloudkeeper Herald was the holiday Familiar for the Mistral Jamboree 2015. The event took place at the end of March, and the beginning of April, 2015. The Mistral Jamboree was connected to the Wind Flight.
The easiest way to obtain a holiday Familiar is to get it while the event is going on. Gather up the right amount of the special holiday currency and use it to by yourself a brand new Familiar. Those that did not obtain it might find some on the Auction House (for very high prices).
