No Havens: What Happens with Nests + Lairs?

What happens in a situation like this? I’ve scanned northern Africa, western Europe. There are almost NO havens. But do nests still form in the mist? If there are no havens in reach, do they eventually combine into lairs? Is this what happened in my previous game when suddenly there were two lairs revealed with the first two haven attacks? (Those two ? are ambushes. :P)

Kinda weird with almost no havens.
