Where did these organisms come from????
The veins of the universe, and the reason why magic works
Really slow squid
Slow flowing liquid that disobeys the laws of gravity and goes upwards
Giants that fell asleep and never woke up (at least the really old trees are)
Big frogs with swords
Halfings' shittier cousins
The evil thoughts of humanity brought to life in the rapidly regenerating bodies of stillborn infants
Weird people shaped things that form out of nasty holes in the ground
Monkeys that got too smart and now they kill people
Lizards that drank demon blood and now they're big
The personifications of greed
what happens when you accumulate too much wealth and don't spend it
War machines from an ancient age
False men, monkeys evolved to look like children so they can sneak around by night.
What humans become if exposed to a strange disease.
The devolved creators of humanity, who came to Earth thousands of years ago.
The eyes and ears of faeries, they use them to keep watch on humanity
The reincarnated souls of wizards and witches
Chimeras and manticores and other monsters made from bits and pieces of other animals are:
The result of teleporter malfunctions a la the fly
A bunch of animals sewn together by scientists/mad wizards
The kids of people who reproduced with demons or faeries
Dreams given form
Oozes and slimes are:
All the fluids in the human body that refuse to die and just keep living
Swarms of tiny, tiny, gnomes
God got stabbed and his blood became ooze
