I like the concept and potential in the name of the playbook. But the name doesn't seem to fit the background choices, which seems to center more around being feared and an outcast, than being a stranger.
For what it’s worth, I named this playbook as more of a pun relating to the fact that characters choosing this class are “Strange” but I also included several backgrounds that specifically make the Stranger a newcomer (or stranger) to the community of Stonetop.
