This page offers a guide on where to locate and how to complete The Wayward, which is a Mystery located in East Anglia.
Speak to the Girl on the Docks
This Mystery is located on the northern shore of Northwic, to the east of the docks. You’ll find a girl named Asta shouting for her horse. The horse won’t come to her, so instead you’ll need to locate the horse and bring it back to her.
The horse is conveniently located on the otherside of the river, just near another pier. The water is also shallow enough to ride through, so once you’ve mounted the horse, ride it back to the girl to complete the Mystery.
