Time for a map to show where everything's happening (and is about to happen!)
Spoiler note: it's not called Doriath yet. :)
For the record, the mountain range on the right of this map is, by my calculations, roughly as long north-south, and is in roughly the same geographical location/latitude, as the British Isles in our own world. That puts Beleriand under the Atlantic Ocean in our present-day world, which sounds about right.
Part 207: Call the exterminator
Next time: Part 208: first battle of Beleriand
