Grimm

Grimm are a magical race that thrive by consuming the sins of other living beings. They are rare, but have been worshiped in nearly every culture in history. Some cultures even dedicated rituals to offer sin to them to have the Grimm protect their villages, towns and cities. These rituals have mostly died out, but some underground cultures and cults still exist and practice these rituals today.

Diet
While Grimm can sustain themselves for a period of time on other sources of nutrients such as meat, berries etc., their primary source of food and nutrition is sin or the darkness of the sin inside of a person's heart.

Appearance
A Grimm is typically a humanoid creature, having most features that a human does, however they can also be in the forms of other humanoid creatures such as vampires, werewolves, elves, etc. However, there are other monstrous forms of Grimm that are much more dangerous.

The monstrous Grimm are less common, but are incredibly dangerous because they're creatures that scour the earth in search of sinful souls to devour. Often compared to demons, these Grimm are the unevolved creatures that were left behind when the Grimm became a sentient creature.

Psychological Characteristics
Grimm have a complex personality. They are chaotic, cruel and perhaps a bit tiwsted, but they can also be forgiving, nurturing and loving. This duality can be traced back to their links with the forces of destruction, chaos, and redemption. For centuries, or maybe even longer still, Grimm have played a large role in the development, destruction, redemption and renewal of communities, cultures and entire civilizations.

Grimm are the embodiment of the forces of change that keep individuals, communities, and civilizations strong through the purging of weaknesses and sin. As such, Grimm have little tolerance for self-righteousness, self-pity, and can be horrifically vicious when presented with such mortal failures. Despite this, they can be inclined to hold patience (at times) towards those who are actively trying to overcome their weaknesses, though this is hardly a guarantee, as Grimm have a notoriously short supply of patience to share.

As impatient as they are, Grimm are perhaps even more underhanded in their endeavors. Many Grimm have been known to rely on churches and clergy that specializes in hearing the confessions of others' guilty thoughts and actions, and then providing instruction on how the sinner can be purged of their sins.
