What I want to know, <name>, is whether this taint is reversible or not. I want you to collect soil samples from this area so I can study them. Perhaps with time we can set things back to normal.
Are you done collecting the samples I asked for, <name>?
Excellent. I will cast an augmentation enchantment on the samples so I can more clearly analyze the taint on the soil.
