Quest: The Fires of Talar

Where?
The players come to a village where all the villagers are greatly suffering.
Many are throwing up and others have died with burns and blotches all over their skin. The plants are also visibly failing.
They all report of a great light to the east two nights prior, it dimly for a few hours and they all went up to observe it. Eventually it started flaring, lighting up the entire mountain range. Those who went up to the hill for a better look were the first to fall greatly ill, the others have been getting slowly more sick.
Strangley, some households have been completely fine, despite everyone having mingled together this whole time.

Secrets: The citizens are suffering from radiation poisoning, especially significant for those who went up the hills to watch.

The people who are not getting sick the ones who drink from the south well, rather than from the river which comes down from the hills.

The only true solution is for them to stop eating the local plants and food and evacuate the town (needs lots of persuassion). How to identify the radiation poisoning:

Sufficient Knowledge: Ferrology can identify the effects as symtoms of exposure to Linear Intrinsic (Elemental) energy

Sufficient Deduction can identify the ever-present feeling of Linear Intrinsic (Elemental) energy

- Even better deduction could identify that the energy is more significant in areas downstream from the hills and identify safe spots
