TO BUGBEAR, WILLIAM, AND OTHERS
The emissaries to Earth are quietly approached by a man calling himself Louis Pasteur.
And this Louis Pasteur explains the situation.
'I am a member of the Silver Cabal, an organization of scholars, historians, and mages - yes, there are mages on this world of Earth - who are dedicated to defeating the Red Death.
The Red Death ... we are not exactly sure what it is, but we understand enough. It feeds off of misery, it flourishes off of pain, fear, and horror. Human misery is it's ambrosia.
However, magic was it's food. It feeds off of magic. Magic, and the use of magic, makes it powerful ... magic is what made it powerful on this world, enabled it to take over, which it has done.
In feeding on magic, the Red Death corrupts magic and all who use it into monsters that serve it.
It is extremely perilous to use magic on Earth, and those who do so almost inevitably fall to the Red Death and become it's servants.
Now your world of Toril is under attack by the Red Death, for the Red Death followed your people back to your world ... by coming here and returning, they opened the way for the Red Death to invade your world.
You say you have Faerie, have great mages, have societies of magic, have priests who throw spells?
Our ancient histories on Earth speak of our own Faerie, of magic using societies, of priests ... they are all gone. The Red Death took them millennia ago.
The Red Death will take your people too, unless ... unless you stop using magic.
You must stop using magic. You must forswear it altogether. I do not know what manner of magic you possess ... your descriptions are confusing to me ... but you must not use magic.
Those of your people like the Faerie, must not use magic. We do not believe the Red Death can affect anyone who willingly forswears magic ... even if the being is innately magical, although we are not sure for certain.
We repeat, you MUST STOP USING MAGIC. The only hope for Toril ... is in science.'
'The Silver Cabal is pursuing science as a weapon to defeat the Red Death. Through understanding and enligtenment, we hope to raise the condition of our fellow men above the misery and despair imposed by the Red Death.
The illness attacking your world is called chickenpox. We have developed an antidote for chickenpox. We have the tools to halt the disease, to stop it from killing your people. Without magic. Without arcane lore of any sort.
Our weapon against misery, disease, and horror, is science.'
'We offer to come to your world and work with your Dauntless. We offer our lore on the Red Death. We offer our science to your people ... for only through science in our opinion can you hope to defeat the Red Death.'
'Will you have us? We have fought this opponent for centuries. We know it's ways. We know it's tricks. We know it's incredible strength. And we think we can defeat this monster, and banish it from your world.'
