On your left, you have Beluaterra on March 4, at more or less the maximum extent of the Blight. On your right is Beluaterra today.
Most of it is self explanatory, but one little thing I thought I'd point out is how the Blight in the sea south of Enweil has started to fade away (you can also see it too a lesser degree west of Sint). A nice touch from Tom imo.
