Wanderer's Ghost

Urban myths across the continent of Savorah speak of a ghost that can be encountered all over the place. The ghost is that of a former explorer in life. The ghost can appear as flesh and blood or a more ghostly visage, they have never been a danger themselves but have led others to misfortune on accident. The ghost wears a traveling cloak and a backpack loaded with supplies. They have books recording their findings and map scrolls tied to their pack, they look to be human but there are some variations in the tellings.
The legends say the ghost was formed by the explorer's desire to see everything there was to find in the world, that their spirit can't rest until they have done so. Others say they made a bargain with an otherworldly power to be able to see everything in the world and until they do they will persist. A darker addition to that legend says that they have their mind erased every time they are about to accomplish their task and so need to explore everything again.
The ghost can be interacted with and has notes and journals that contain a great deal of information from before the cataclysm. It doesn't seem to care or know much about who they were in life only that they want to see everything there is. Often there is also mention about how he is tired, or that it is getting cold and he just needs a few minutes rest. Those who have heard the ghost speak about this assume that they died in the cold. If you are able to copy from the maps it carries it could reveal many hidden places, the ghost may remember being there but only has a vague remembrance of what inhabited the area or traps in the area. It might respond with "I remember seeing trap triggers." or "There were large creatures in the area, I don't remember the name but I think they were aberrations?"
