Ents are fictional tree-like creatures from J.R.R. Tolkien's Middle-earth, primarily featured in The Lord of the Rings. They are known for their slow movements and deep connection to nature, acting as guardians of the forests. Ents resemble trees but possess the ability to speak and think, often referred to as "tree herders." These beings are characterized by their wisdom and strength, often taking a long time to make decisions. They play a crucial role in the story, particularly in the battle against the destructive forces of Saruman, who threatens their forest home, Isengard.
