“ To purify the water from a certain river the monks have carved a section of the river that goes over a stone bed. Through holy carvings of gods, godesses, and holy symbols and then the river flowing over them, it purifies the water making it safe for drinking and/or makes it holy water. For rivers that do not have natural rock bottoms, large smooth stones can be carved and added to the water to fully cover the bottom.”
“ A common mistake when writing adventures set in deserts is to assume that the climate is too ferociously hot to wear armor. Historically, most battles in deserts involved troops dressed in protective armor. Although they would have been miserable during the hottest part of the day or the hottest part of the year, desert weather isn't intolerably hot 24/7.”
“ Along the sluggish Vanne River, the banks are lined with thick stands of tall bulrushes. These areas of wetland are considered ill-omened by the locals, for they hide the skeletal remains of thousands of grazing animals, washed downriver in a terrible flood decades before.
Adding to the uncanny reputation of the place is the occasional undead cow or goat that lurks there. The product of a necromancer's experiments some years before, these relatively harmless undead wander the area at night, startling livestock as they attempt to graze with them.”
