Whenever you approach a wayshrine (wether or not it need to be in reapers march is unsure, but it might), you will be approached by an npc. This npc will stay at that wayshrine for you!
There is a know bug on the console that npc's don't show up. they are there but invisable. You see the option to interact but it is greyed out. This is often solved by logging off and on, but when the npc did spawn invisable at the first wayshrine you visited, it might be hard to remember which one.
The known bug is listed as "Will be improved in the next patch" in this thread: http://forums.elderscrollsonline.com/en/discussion/173858/esotu-console-launch-known-issues/p1
