“ Elves use nature as strength and borrow from the trees to keep them living. An elf out of the forest for more than a day begins to die and within 3 days is dead without borrowing the strength of nature.”
“ Idea from the Aeneid. Could make an intriguing encounter when searching for firewood...'Quite near there happened to be a mound of earth, at the highest part of which were growing thickets of cornel and a dense cluster of spiky myrtle-stems. I went up there and tried to wrench the green growth from the ground to provide a leafy covering for our altar. There I was confronted by a horrible and astounding miracle. For from the first bush which I tried to break off...blood oozed in dark drops, fouling the earth with its spots...A piteous moan came from the base of the mound and I heard a human voice answering me: 'Why, Aeneas, must you rend a poor sufferer? I am buried here...for I am Polydorus. Here death overpowered me in a crop of piercing iron-pointed spears. And so a crop resembling javelins has grown over me...''”
“ After the PCs defeat (or force the rapid retreat of) a villanous necromancer/demon summoner, they discover a book. This book outlines how to summon a demon whose power increases according to the size of the summoning circle used to summon it. And after the PCs examine a map of the country, they find that the layout of the cities and roads match up with the required summoning circle. In fact, the final road that would complete the circle is currently in construction.
With anyone who can find out about the circle and the ritual to summon the demon able to somehow make the final road/line, and destruction of the cities and roads currently in existence out of the question (unless this is an evil campaign- that removes the moral quandary), how are the PCs going to solve this problem?”
