The Oathbreaker undead lich knight thingy really doesn't need to hang out at the camp like hired help.
With very little effort, there could be an item, an altar, a dream.. anything to contact him in some dreamscape / off world / anywhere but the freaking camp.
I really hope him and Withers having nothing better to do is just some haphazardly put together Early Access thing and it won't be anything like that in the final game. Either it's that, or Larian just really know how to destroy any feeling of mystery and awe in their game and thought the camp "works great" for those interactions.
