The Radiance wiped out the people of Blackmoor and all those who were near the reactors. What life remains in its aftermath? How was divine magic effected? What remains of Blackmoors Legacies? Is Technology hoarded or destroyed by those who would attempt to prevent the destruction of the world yet again? What creatures arose from the wastelands spawned from the aftermath of the Radiance?

I see, so they were able to create wonders of technological prowess that wasn't natural for their world due to factors unknown besides ohysics and possibly the magic that radiates from Mystra. If I introduce technology it will be how I've introduced it in my games set in Numeria of the pathfinder setting, they will be built like magic items, they will act like magic items, they will be difficult to build and difficult to use if you are untrained in the art of making and breaking technology down. A pair of boots that create a EMP effects might function like boots of stomping, a storage matrix functions like a bag of holding, night vision goggles function like goggles of night, Data Slate describing how to build 'AI's and Robotics would function like a Golems Manual.

I've also thought of the Egg of Coot as a possiby a old one or great old one whose prison is Mystra but because of his 'alien' nature he feeds off energy and because Blackmoor/Mystra radiates or is infused with magic it became dependent on magical energies. With the introduction of dark technomancy the Egg of Coot discovered a way to collect his food source without having to collect the bodies instead of using brain canisters of alien design his 'disciples' discovered in a distant mountain pass with a strange creature holding a mixture of strange devices.

I can see in the aftermath groups of explorers looking for technology might activate a damaged gate that releases a eldritch influence similar to the Egg of Coot or the Outer Beings but possibly something like Yog-Sothoth, a primordial entity that is the manifestation of time itself but creating a time space dimensional rift letting the region be a hazard zone even the few Immortals of Time have to ask 'what is happening, why is the world falling apart?'

I'm tempted to say that divine magic has begun to dwindle to a bare minimum that those who still recieve blessings from their patrons have begun to sell their skills to the highest bidder. Make it seem that many dont trust science to the degree many of Blackmoors technologist and disease specialist, so many turned back to the gods hoping they would cure the Wasting but many of the gods have become silent in their actions and the few who remain active are those of the sphere of Entropy.

I'll add some fey and possibly half-giants to the list of races, I've wanted to include the races the Egg of Coot may have bred as slaves because what does a slave do when the master is dead or in stasis? They wander out of his domain.Though because I'm using the 3.5 source book the Ash Goblins seem like something that may appear in the aftermath as a race of degenerate goblinoids or possibly a split caste of advance and degenerate goblinoids who were the target of Blackmoor experiments in attempt to breed out the savage instincts of the ash goblins and possibly other races Blackmoor scientist deemed as threats. They might have even created new races like I mentioned the Ratfolk.

Do you mind filling me in on the current affairs of the patron of the Cult of the Frog? Is his amphibious brood expanding from the Froglin?

Also what classes would be appropriate for the aftermath of the Great Rain of Fire? I guess arcane magic is probably a iffy thing that might end up turning into a disaster while divine magic might be rare if you have a patron. Fighters, rangers, and rogues would fill their usual niches and barbarians might be seen among the degenerate tribes who seek refuge but find none. I could see the tribes of wasting mutants being built upon rangers, blight druids, grafters and salvagers, and their leaders may be the greatest of their kind with the most complete grafts and augments and their shamans might be straight up blighters who feed off the effects of the Radiance. Druids might be seen in the dominion of the fey and their twisted cousins might be skilled Blighters who revel in the fallout seeing it as Entropy's greatest manifestation. How would you represent the technologist of Blackmoor though?

I thought in the aftermath of the Great Rain of Fire you'd find Wizards attempting to harness the power of the fallout from the Radiance and the raw power of plasma as their spells, possibly even a few attempting to make new techno lich bodies or delving into mutations of the aberrant nature to try to bring a immunity to the Wasting disease.

That makes me think Stodos didnt have a full plan made to a point, since his followers are the Cult of Frog wouldnt that hinder his amphibious followers? Though the idea of a forzen wasteland sounds like something a demonlord would do to to try and keep his connection to the prime right.

Okay and agreed on the madness of wizards, I like making players search for new spells to add to their spell books and certain tomes invoke ancient evils like the Outer Beings and the ancient Demon Lords of the Abyss and that will cause some madness to manifest in the caster if he has no protection against such things.

I could see the artificer acting well as a technologist whose knowledge in the art of technology only goes so far and they can only support so much tech on their own bio-electric field. I play with the Pathfinder rule set and they do have a exact artificer class but a third party supplement has a artificer who uses weird science to mimic spells. The system does have a alchemist class whose potions mimic spells that affect the caster and have the ability to create mutagens and other thing such as bombs and bodily mutations(Wings, gills, tumors, etc.)

Just saw this thread and am still reading through it, but one version of what happened after the Great Rain of Fire can be found in the forum ;)

Minor nitpick: The catastrophe is called the Great Rain of Fire. The Radience is the name of a powerful artifact that somehow survived the disaster, not the disaster itself.

I also wrote some ideas for a campaign more immediate after the Great Rain of Fire called the (scroll down).
