What is wesen?

Wesen is a term used in the popular TV series "Grimm" to describe creatures that are part human and part animal. These creatures are often based on German and European folklore, and they each possess unique abilities and weaknesses.

Examples of wesen include the wesen wolf, which has heightened senses and is vulnerable to silver, and the wesen fuchsbau, which can shape-shift into a fox and has an enhanced sense of smell.

In the show, there is a secret society of Grimms, who are humans with the ability to see wesen in their true form and are tasked with keeping them in check. The main character, Nick Burkhardt, is a Grimm, and the show follows his adventures as he navigates the world of wesen while trying to keep his identity as a Grimm a secret.

Overall, wesen are a fascinating and integral part of the Grimm universe, adding depth and complexity to the show's mythology.
