How do we know where they will be if they do?
So far.....Each area that has a Stranger has only one.
However, within that area they seem to be able to spawn pretty much anywhere.
So that first one? He seems to only be able to spawn in Despise. But he can spawn
anywhere within Despise.
Per what J has said, only 1 is going to be spawning at a given time.
We won't know which area is going to be hit, unless they start telling us, and we won't know where in that area the spawn's going to be.
