You have updated the 'no tech' to include gunpowder, that is good to know. Thank you for keeping me informed of that.
Does fire still work? Can you boil water? Candles? Oil lamps? Bellows? Windmills? Animal drawn/powered mills? Trying to confirm what other basic things 'do not work'.
No notes about the effects of the mists on an exposed individual.
Are we talking about the RAW teleport table/rules or something else? I get that 100% they can't return through the pocket, but leaving that way looks viable from the information I have been provided up to the point.
