A Brief Guide to the Beastlands

The Beastlands is a widely misunderstood plane. Visitors think that it's an excellent hunting ground for big game, for sport, and for trophies worthy of the greatest hunter, but this impression is exactly backward.
The Beastlands is a plce where animals and beasts of the field are stronger, smarter, and quicker than they are anywhere else in the multiverse.
They speak and understand the Common speech., and they hunt those who dare to visit them.
Thus, the proper attitude here is not arrogance, but humility.

In like manner, most planar travelers think the Beast Lords are just friendlier versions of the Demon Lords of the Abyss, a big smiling Monkey King,a regal but kindly Cat Lady, and a hissing Lord of Snakes.
This impression is likewise erroneous.
The Beast Lords are embodiments of what a given animal kind thinks of itself, not what humanoids and outsiders think of it.
So the Monkey King is smarter than you think, clever with tools, and able to make prodigious leaps. The Cat Lady expects her due from visitors in offerings of food and respect, and interrupting her naps can be lethal.
The Lord of Snakes is wise and kindly, and not always poisonous. As the father of great legions of followers who slither throughout the multiverse, he hypnotizes and embraces his enemies as often as he bites them.
In like manner, the Beetle Lord, the Ant Queen of Queens, and the Mosquito Empress might be unfathomable to us, but they represent perfection to their followers.

Annoying or attacking a Beast Lord earns you the undying hatred of all its kind. If a Beast Lord attacks you, however, you cannot be blamed for defending yourself, because predation is a way of life in the Beastlands.
Prey and hunter are two sides of the same coin, and to the Beastlord, you are prey.
