D&D 4E How would you re-envision Darksun with 4e?

[Dr. Halflight]

Those are awesome defiler powers that I WILL be using (darksun is soon to hit our tables)

How about "Wither the World" for Blacken, it just sounds like a 4E power name (like "Split the Tree")

Thank you. That is nice, I've also been thinking about Despoil.
