Jep. Sky has sent out a few units and advies to do some scouting but with no success. Captured by rogues upon landing.
Also Candiels was overrun by 60k CS of monsters, pretty much putting those plans on hold indefinitely :p
Did you try "delaying arrival"? Usually, when you are in-between regions, 1 hour away from your destination, you get to look around, even if it's a sea route.
But indeed, I think we'll need the League to get together to bash at one city at a time, because everyone on their own I don't think any would succeed.
