"You are being hunted" is the only event that can happen outside the trigger range of three base structures. It may take place in any of the active biomes (Meadows, Black Forest, Seamp, Mountain, and Plains). Other events in these biomes require that a viking occupy a base, an area in which three base structures are within trigger range. Consult the Valheim wiki for a list of base structures.

konstantinoskountousias has had the bad luck to have four "You are being hunted" events in a row. And yes, konstantinoskountousias, "being hunted" outside a base is perfectly normal.
