This page offers a guide on where to locate and how to complete Mother, which is a Mystery found in Essexe.
Save the Woman
This mystery is located southeast of Halstead Outpost. When you approach the house, you’ll find that it has been surrounded by wolves. Your first task is to take out all the wolves in the surrounding vicinity. Then, the woman will call out and request that you find some flowers for her, otherwise she won’t open up the barred door to her house. The flowers in question are found growing out of a grave nearby, you can use Odin’s Sight to help you locate them if you need help.
When you’ve got the pretty flowers, head into the house to discover that the damsel in distress is actually a lonely man. You’ll need to speak to him and tell him to move on from his lonely home to complete the mystery.
