And frigging undead everywhere.
I've noticed a bit of a resurgence, mostly through word of mouth. Are they starting to appear out of the blight in greater numbers than previously? There was a while when there was hordes of them, but then they kind of tapered off for months... If they are starting to grow in number again, one has to wonder why...
I think it would be a very interesting idea for a fifth invasion if rather than the invaders suddenly showing up out of the blue, they just started slowly creeping out of the blight in larger and larger numbers. I wonder how long it would take everyone to realize what was happening and start to respond. How many realms might be critically weakened before that happened?
