“ Giant mushrooms the size of trees. The stems and parts of the caps can be used in construction, and only the gills are soft enough to eat. An entire fungi-forest can grow in a matter of days, provided the correct conditions. Most fungus trees last about a month before collapsing, but not before a new generation sprouts to provide shade for the next spores.”
“ Another real world thing. White tea. Can only be picked two days a year, the two days before the flowers blossom. Could be a similiar plant that...is the deadliest poison known, cure known diseases or psychosis, or a potent herb that just tastes awesome.”
“ A good camping-place with something extra: a gallows with a hangman, reduced mostly to bones and a few rags. It marrily hovers in the wind. Any manipulation will make it fall apart. An excellent camping place, except for the midnight hours, when ghosts of those executed haunt here. Some wail for their crimes, some re-live their execution over and over, some want to have a talk, and still some others want to scare the Living for fun.”
