The Bald Beaver:
The bald beaver is type of rodent that is about 3' long, including the tail, and ranges from 20 to 40 lbs. It's body's coloration ranges from light brown to black. The fur on it's head on the other hand is always white which gave it it's name.
It's most interesting parts are wings with a 3 foot wing spread. A large flat tail, that can make a surprisingly loud noise when slapped against water. A set of long claws on it's front feet to allow it to catch fish and carrying logs. And finally two large front teeth in it's mouth that it uses to cut down trees.
It's habitat is the mouth of rivers that proceeds to dam partially so that it can build it's lodge and create a primitive fish weir. While an omnivore the only meat it will hunt for is fish.
It's origins lies with a wizard trying to end a feud between to nations. Important note, if you come across a family carrying a log back to their dam do not startle them. Their natural instinct is to drop the log on the on what ever is threatening them.
