I was walking down some steps in Haven, just the right size for Knights to traverse, and began wondering how Strangers manage these stairs. Given their size, their feet would be too big for them. Looking at Haven from this perspective, I noticed that most of the buildings were too big for the Strangers as well. Did we build all this on their land? The other theory I thought of was that Strangers move on a slug-like undercarriage, and could compress their bodies to go through doorways. Maybe they're an independent, friendly kind of slime monster. There's a lot we don't know about them.
