Grimm

The Grim (possibly Grimm) are monsters introduced in RWBY's pilot episode. They're described in the opening narration as "creatures of destruction".

The Grim are said to have first appeared not long after the dawn of mankind. They sought only to destroy man and all of his creations, and it seemed as though they would succeed. However, after humans discovered the power of Dust, the Grim were driven back, allowing human civilization to survive and prosper.

The world of RWBY currently enjoys a time of peace, but the pilot's opening narration suggests that the Grim will soon make a resurgence.
