Some Answers:
Edena:
I will try to determine what long term damage the Sunbane and the Blood Waste will have on Oerth if left untreated. I am determing not only the effect on the planet, but on life.
ANSWER:
Obviously, they will have an ill effect. But 11th level magic will heal both.
How ill an effect depends on how long they exist - the longer they exist, the greater the ill.
I will consult with the Silent Ones of Keoland and the clergy of Beory the Oerth Mother, perhaps the oldest of all beings in the Greyhawk cosmology.
ANSWER:
The answers you receive are from the Silent Ones and especially from the clergy of Beory.
The clergy of Beory are extremely alarmed.
I seek to see in what ways these threats can be reversed or mitigated.
ANSWER:
If the goo is spread, the problem is spread.
However, without the goo, no red metal can be produced.
The Oerth Alliance advises extreme care be taken by those powers who have grabbed some of the Blood Waste. This is a very toxic substance.
ANSWER:
You are stating the obvious!

The Solistarim are churning out armor and weapons with the material.
The Alliance of the Crescent is churning out Red Golems from an offplanet refinery.
The Shade are throwing their power into strengthening the Blood Waste and they have specifically stated they are increasing the rate of Shade Poisoning of the world of Oerth.
The Dark Union, undoubtedly, is mass producing armor and weapons of red steel.
The Torilians cordoning off the Blood Waste are feeling the effects of the fumes.
Many Torilians become ecstatic, their senses and powers heightened drastically.
Others become very ill, and are put in bed.
Others seem unaffected.
There is no effective way for the Torilians to move their cordon far enough out from the edges of the Blood Waste to avoid the fumes.
Especially since they face battle on the east side with the Shade.
And because, simply put, the Blood Waste is too big.
I am awaiting to see what Kalanyr does, since he has 10th level magic and can pierce the blockade.
