I was looking to see if there was a poll thing I could do, but I didn’t find anything.

We have three settings we can go with: Pre-Fog, Fog, and Post-Fog.

Pre-Fog is more investigative and not knowing anything including not knowing the fog is the main problem. There will be slight research that the fog could be a problem. 

Fog is more panic inducing for the populace. Stuff happens and usually people go missing but are either found or confirmed dead. The fog at this point is a dying effort for research since people who enter usually never come back.

Post-Fog is more silent hill style. An alarm will blare and people will run for their lives and the fog is a lot more aggressive, but so are the people. Military involvement, PMC, you name it, they are there somewhere trying to help out but usually getting massacred. People have given up on researching the fog because it is always looming at the lake. It spreads randomly and sometimes multiple times a day and it can linger for weeks. Small amounts are confirmed save to travel through, it’s the thick walls, such can be seen at the lake, that people avoid at all costs.

Time framing would be approximately… 60 minutes of light fog, 90 minutes it becomes thicker, and after 120 minutes it is at its thickest, imposing, and lethal form.
