“ A desolate region is almost entirely without normal vegetation. Local plants are able to unroot themselves and crawl along the ground in search of water and fertile soil. The inhabitants fence their crops in to keep them from wandering off and put heavy stone thresholds in the doorways of their huts to keep wayward plants out.
The plants sense by chemical cues, lacking sight or hearing, and tend to avoid herbivores or anything that smells of 'dead plants'. Characters with horses are likely to be unwelcome among the locals.”
“ In the far reaches of a long-lost wilderness, there stands a forgotten town inhabited only by children. Though they appear normal enough, their eyes burn with madness, and they speak in a foreign, archaic tongue. Nearly a millenia ago, a powerful spell had gone awry, or maybe it had succeeded - in any case, it ended up blessing, or cursing, an entire generation of children with agelessness. However, as the centuries passed, the children's parents grew old and died, the buildings of the town crumbled to earth, and even the civilization itself faded into history, becoming lost to time. All that remained were the children, driven mad by the psychological toll of living for hundreds of years beyond their age. In time, most children died, killed off by fighting amongst themselves, while many others were driven to suicide. Only a small handful remain, and they are a strange people indeed.”
“ Patterns in surnames: There are many ways a surname could have evolved over centuries. One possibility is migration. A Roman name may have traveled to France and hence to England where it was later Anglicized. Case in point - the surname Lawrence went from Laurentius (Roman) to Laurent (French) to Lawrence (English) and then to Lowry (Scottish). There is also natural etymological evolution. For example, a Middle English spelling may have evolved to a modern English spelling (e.g. Stiward to Stewart). Where did your character's Surname come from?”
