Zaun Werewolves age and mature at the same rate as basic humans but tend to grow a lot more hair at younger ages.

Since they have a taste for blood and are werewolves they tend to lean towards evil, butt in the rare case a werewolf learns to control their thirst for blood they can become Neutral. There are possibly one werewolf that is of the good alignment so it is very very rare.

They tend to have the same height as humans possibly a little taller. So they range from 4 to 7ft tall

Since they tend to use all of their limbs for walking and running they have a walking speed of 40ft. They can walk on their hind legs, but they usually run on all fours.

The werewolves of Zaun have adapted to the many alley ways and toxic building they have to run through to chase their targets, so they have gained the ability to see in the darkness to give them the one up on their prey.

The werewolves of Zaun can smell blood from a very far distance so they can track their targets all across the city and never let them escape. They gain a rush of adrenaline at the smell of blood that allows them to hunt their targets down even faster.

The werewolves of Zaun have learned to feast off of the blood of their enemies in order to cure their wounds. So you can use your jaws to make a natural weapon attack dealing 1d6+STR Modifier piercing damage. Then you heal for half of the damage dealt from your jaws. 

You use your natural skills of hunting and tracking your targets along with your adrenaline rush from the smell of blood to leap and tackle enemies to the ground grappling them.
