So back to Glantri and the Radience.
As can be read in my earlier post viewtopic.php?f=3&t=15838&p=202916#p197003
I have made 8 mile hex maps of the remains of Glantri while and after the Blast.

This is the Year 1751 AC when the Radiance explodes.
8 mile hex map
Glantri is destroyed in the blast and any remains dissapear in the subsidence zone(where the ground molten will sink up to 300-400 feet https://sta.sh/026w73dev35g)
, rapidly covered by a lake, which deposits the radioactive waste at the bottom of the lake.
1 Explosion (Yellow Line on map)
Fireball starts to form in less than a millionth of a second after explosion, several tens of million of degrees: transformation of all matter into gas/plasma, creating thermal radiation as x-rays, which will be absorbed by the surrounding atmosphere.
The explosion reaches 440 ft in one millisecond, 5,700 ft in 10 seconds, but subsides rapidly; after one minute: cooled, no longer visible radiation. The formation of the fireball triggers the destructive effects of the nuclear explosion to 200 miles up. All Elemental Planes in the ground are instantly dispelled and disintegrated. Maximum size of the nuclear fireball; radius: 8 miles (the initial Hex of the city of Glantri).
2 Radioactive Cloud (Red line on Map)
During expansion of the fireball, vaporized matter condenses to a cloud containing solid particles of weapon debris. The Fireball becomes doughnut-shaped, with violent internal circulatory motion, while Air is entrained from the bottom, creating a “mushroom” cloud of dirt and debris sucked up from surface. The blast melts the underground materials, destroys cellular structures and causes a subsidence zone (see graphic right).
3 Air Blast/ Shock Wave (Orange Line on Map)
Pressure wave develops immediately after explosion and moves outward from the fireball
After 10 seconds: diameter of fireball: 5,700 ft, distance of shock front: 3 miles from the surface centre of the explosion (the GSM). The Wave is reflected from surface, both waves merge to create “Mach wave”. The Portal to the Plane of Air will absorb the brunt of the upward Blast and heat, instantly increasing to a size up to a few hundred yards, collapsing soon thereafter due instability, dispersing the radioactive cloud, heat, shock wave, air blast and blown up debris into the Plane of Air (creating an elemental polluted zone there).
Air blast radius (20 psi+): within the initial Glantri city hex causes heavily built stone buildings to become severely damaged or demolished, all other are disintegrated by the blast and fire, fatalities approach 100%.
Air blast radius (5 psi+):within yellow circle causes most residential buildings to collapse, injuries are universal, fatalities are widespread.
Thermal radiation radius 51.4 km (8,290km²)
4 Thermal Radiation (Red Line on Map).
Reemitted radiation from the fireball creates a secondary thermal radiation (3rd degree burns): Duration: about 10 seconds=1 round (99% of total thermal energy).
5 Initial (prompt/Direct) Nuclear Radiation. (Yellow Line on map)
Radiation releases within the first minute, mostly neutrons and gammas (directly from the explosion or from fission products) dispelling ALL magic in the region.
6 Delayed Nuclear Radiation / Fallout (Grey Line on Map)
Caused by material lifted into the fireball right after the explosion, mixed with radioactive residues of the reactor (activated debris, fission products, ...), a delayed radiation effect and fall out will take place following the dominant wind (N to NW) with further devastating effects; 98% instantly killed in the yellow circle, 50% within the red circle, (40% wounded), 5% killed in the orange zone (45% wounded), 25% wounded within the pink zone. The amount of radioactive fallout is significantly increased due the fact that the explosion was underground. Any creature in the orange zone will have a
7 Mass fires (Red Circle on Map)
Initial fires (started by the thermal radiation) combine and form “super fire”, about 20 minutes (2 Turns) after the explosion. High velocity winds directed towards centre of fire cause a “chimney effect”. Gates to the Plane of Air ruptured causing fires to enter the Plane of Fire. Death caused by heat or suffocation.
there is 100% probability for 3rd degree burns; these extend throughout the layers of skin, and are often painless because they destroy the pain nerves. They can cause severe scarring or disablement, and can require amputation.
Without medical treatment, there can be expected between 50% and 90% mortality from acute effects alone within the red circle. Dying takes between several hours and several weeks.
Severe earthquakes are triggered due the subsiding, within the red zone, and medium earthquakes in the pink zone.
8 Wasting Disease.
The survivors suffer wasting disease within the Pink Circle, miles away from the initial explosion; Within 10 minutes (1 Turn), 100% of the survivors will be affected, and perish in 4d12 Hr by failure of the nervous system within the yellow circle. Within the red circle after 3 turns 9+1d10% of the survivors will be affected, and perish in two weeks by failure of the intestinal system, Within the orange zone, 40 miles away from the explosion 1d10-10% of the survivors will contract wasting disease in 1d3+3Turns, becoming lethal in 1d4 weeks by failure of the blood system. Further in the orange zone each individual has a 50+2d20% chance to contract Wasting Disease, which is 1d10-10% lethal in 1d6 weeks by failure of the blood system,

It is after the Year 1751 AC.
The Radiance has been exploded...with devastating effects upon its region in an already changing world
Within the initial hex of the city any structure will be utterly destroyed by rock vaporized, seismic shockwaves, superheated radioactive gas, earthquakes. The whole hex of Glantri city will be destroyed, and subside several hundred of feet, becoming inundated by the rivers. Any creature in the yellow zone will have a 100% (-1% cumulative per year) chance per week to be affected by the wasting Disease.
Within the Yellow circle many fires, will have caused heavy damages to structures, wooden structures are all destroyed (including Forests). Any creature in the yellow zone will have a 50% (-1% cumulative per year) chance per two weeks to be affected by the wasting Disease.
Within the orange zone light damage to structures, some fires Any creature in the orange zone will have a 10% (-1% cumulative per year) chance per month to be affected by the wasting Disease up
Any creature in the pink zone will have a 10% (-1% cumulative per year) chance per year to be affected by the wasting Disease.
Any creature in the grey zone will have a 10% (-1% cumulative per 10 year) chance per year to be affected by the wasting Disease.
Any creature in the fallout hexes (light grey=dust)will have a 25% (-1% cumulative per 10 year) chance per month to be affected by the wasting Disease.
Several rips between the planetary cells cause the water to slowly to dissapear underground...creating a stable lake which no longer feeds the rivers south(The shadow elves break of any contact with this deadly region, and divert the river of death where they can....eventually it will reach the Worldshield, be evaporated, condensed, evaporated again, and cleaned of radioactive waste...this will take decades to several centuries, but eventually the water will reemerge on the surface throufh several wells.
The region is severely radiated and will cause mutations of the few surviving creatures.
As the Radiance had effects upon Magic, and magic is prevalent in Glantri, the explosion did have great effects too. Many negative Magic locations came too be within the affected region; the effects of these range from anti-magic zones to areas with powerful negative effects (some could have effects like the World Mountain—see GAZ12-TSR9246-D&D-Mystara-The Golden Khan of Ethengar).
As the Planet is a creature biological processes will have a counter reaction creating Good magic zones outside the affected areas; these could have a diverse effect too ranging from elemental location, to similar to the zones in Alfheim (see-- GAZ5-TSR9223-D&D-Mystara-The Elves of Alfheim).
Within the already changing world the nation of Glantri completely ceases to be. The regions unaffected or less affected start to recuperate the loss and become separate regions. The areas Southwest of the Glantrian Alps take benefit from the waters from the Great Crater, and the new good magic points, surviving Erewan Elves settle here. The various regions combine together in the Confederate of South Glantri to remain powerful enough against the Humanoids of Kolland, Orcus rex, and Ogremoor. The areas against the Ethengar border become New Glantri, where Belcadiz elves and various humans are present. The new good magic location creates balance to them, and a more positive inclination towards Ethengar. Ethengar already has adapted to the lakes, and several have lost their tribal heritage. This side is more at peace. The regions of the northwest also recombined into the Domain de la Nord (The Northern Domain) with many effects still as before the disaster. In the North the provinces Aalban and Klantyre exist along the Forbidden Zone, but although these reflect a lot from before the disaster, fall out greatly affected the nations. Klantyre and Aalban have extended their original borders incorporating the remnants of lost principalities. However, this caused great dissension between both nations and the conflict still continues. The former principalities in the far north still exist, but rulership changed greatly, the undead lost their dominance and taken over by the Followers of the Claymore in an attempt to pacify the region.
The Humanoids of Gobbleton have taken over the former Glantrian town Trintan, which now has become a Freeport for all. This is the most used location to venture within the forbidden zone. The Site Interdit Mortellement (or deadly forbidden zone) is off-limits to most from all other directions. Several towers have been erected by neighbouring regions to supervise what is happening within. Many mutated creatures, monsters and several surviving undead still reside within, but all suffer from radiation or the Wasting Disease.
