“ Feral teenagers:
Teenagers who run away from home to live in the wilderness may become feral. As they become more and more feral, they gain some supernatural powers (a la Peter Pan - ability to fly, things they imagine come true - possibly quite powerful), but at the expense of their humanity and ability to speak, comprehend complex subjects, etc. Maybe they have a leader: the most feral of them all.
A regression into a fantasy childlike state.”
“ A wild species, vinus homophagus, more akin to sea-grape rather than the terrestrial variety, is not a monster despite its fanciful name. The grapes, a deep purple color when in bloom, and oozing dewdrops of perspiration, like the most prized and delectable of drinking wine grapes, do however deserve their moniker. Wine made from this fruit, is deadly to most humanoids, as is the raw berry if plucked and eaten from the vine. It is the unnatural chemical concoction found within the fruit's tart skin, which gives the man-eating grape its name. The chemical stew found inside each berry, functions as a necrotic agent, the same as found in some species of venomous snakes.
The grapes literally eat their victims from the inside out, via cell death, melting and destroying the organs in quick succession.
The tribes of Pra-Oohk Crater, of the jungles of Ghlush are known to sell the fermented 'wine' of this grape to merchants of distant lands. Sadly, the taste of the concoction is divine when first quaffed, and even worse, the man-eating grape wine will never detect as poisonous via mundane means, its horrid natures somehow masking all attempts. Luckily the man-eating grapes are extremely rare, and endemic to humid jungles.”
“ The PCs see a large oak tree, a curious species of yellow and black butterflies swarm around it. Upon further inspection they find that the tree is hollow and that there is an underground cave in it from which the butterflies appear. Will they inspect this strange cave?”
