The authors of Mediaeval bestiaries were not merely concerned with providing a description of creatures. No, for them, everything in Creation had a purpose - nothing had been made without an ulterior aim: the edification and instruction of sinful man. So, each creature described is not merely an animal but a living parable, imbued with moral or religious symbolism.
Sacred bird of Raelis, the Sunfire Laerti is a bird of prey, a perfect flyer and fearless predator.
Omen Birds are the harbringers of death and bad things to come. They accompany war/ battle, monsters, pestilance, and disaster. They follow the bringers of such as well as selecting their victims.
A fey hound is a majestic animal, blending feline and wolf aspects to form a complete graceful animal.
The best way to describe these creatures, 3 legged chicken/monkey/squirrels. These animals are proof that Gods have senses of humor.
The Golem moss is an amazing lifeform, and is able to survive in nearly any environment. Its evolutionary rate is far higher than any other creature on the planet, enabling them to adapt.
This slug like parasite is actually a symbiote. After attaching itself to a warmblooded host, it feeds off that being. However, its tenticles, growing under the skin, act as secondary nerves, increase the victims nerve responses.
These mites fly silently and are small enough to be nearly invisible to the naked eye. If it was not for light, no one would know they were there. These creatures absorb and re-emmit light, turning dim to bright, and bright to blinding.
Globs are a partially amorphous life-form of the shape-changing kind.
Fakastr are large brutal bull-like creatures. They are green and brown mottle in their fur. Their hooves are large and sharp, as are their long pointed horns. They also regenerate. If they were not dangerous enough, they are semi-intelligent.
Blood Spiders are dark brown rust color, nearly the color of dried blood and have a body that is approximately 5’ wide, not including their legs. They have a desire only for survival and are not malicious. Tell that to one of their victims.
An Aoktholian Swarm is a huge swarm of screeching, red and black feathered crows. The Aoktholian does normally not exist, but when there is a drought, these desperate crows change.
Arkths are dangerous creatures: as large as a grizzly bear, armored like an organic tank, strong like a wyvrn, and an attitude that makes them take out anything that gets between them and their “food”. These creatures are destructive to everything around them. That is why they are known more commonly as Ravagers.
Large and powerful, the Yeaken are a beast of burden to be reckoned with. While very domesticated, the Yeaken have dangerous wild cousins.
Drakonus Legitus is commonly know as Order Dragons or (rarely) as Companion Dragons. They are known as Order Dragon for several reasons, the most obvious was that they were used as Dragon Mounts for the Dragon Knights of the Order of Eternal Flame… a mythic order from an earlier time. There numbers in the wild are quite small and there are no captive ones known… at this time. Most of them died with the Order.
Long sieges can be a trial for both sides. For the beseiged especially, finite ammunition supplies always pose a problem - except when the ammunition can reproduce…
This tome looks like a haphazard collection of random notes on different types of paper stitched together and bound within a wooden cover. The pages describe all of the 300,000 gods of the world, each in the language of the people who worship them. The book is stored high in the mountains, kept safe by an order of monks. Reading the entire book confers a deep understanding on the nature of the cosmos and access to incredible power. This only works, however, if it is read without translation, meaning that the reader must master each language contained within. The various monks know these languages but there is typically only one alive at a time who knows them all. This monk would be an excellent source of information and/or magic. IF the PCs learn about it; IF they can find the monastery; IF they can convince the monks to help them; AND if they can understand the convoluted riddle given as an answer.
