When you reveal threat cards and they are a Stranger do they stay on the space or do they travel with the Character?

Strangers never move unless the card says. Strangers don't become followers/assets unless they say otherwise.

I am new to Relic, but have played Talisman for years, and am going by such.

I have 4 games of Relic played under my belt.

thank you

He is correct. They stay in place unless you are instructed to do otherwise
