Giant Ant

Encyclopedia Entry:

A type of insect monster that lives in a group focused around a queen.  They dig holes in plains, and caves, making a huge nest.  In spite of their small bodies, they possess a frightening amount of strength.  They can easily lift and carry objects much larger than themselves.  Besides the queen, the rest of them are called “workers.”  They perform a variety of tasks including defending the nest, procurement of food, and expansion of tunnels.
