Certainly! "The Worms of the Earth" is a significant short story by Robert E. Howard that features another of his iconic characters, Bran Mak Morn. Unlike Conan, who hailed from the Hyborian Age, Bran Mak Morn is associated with Howard's historical fantasy setting called "The Pictish Wilderness."

In this tale, Bran Mak Morn, the last king of the Picts, is faced with a dire threat in the form of the Roman Empire. In a desperate attempt to defend his people, Bran seeks the assistance of ancient and malevolent entities known as the "Worms of the Earth." These creatures are deeply rooted in the supernatural and possess a profound connection with the earth itself.

Bran Mak Morn's alliance with the Worms of the Earth is both a desperate pact and a manifestation of Howard's exploration of the clash between civilizations, cultures, and mystical forces. The story delves into themes of revenge, survival, and the cost of resorting to dark powers to achieve one's goals.

As with many of Howard's works, "The Worms of the Earth" is characterized by its atmospheric storytelling, vivid descriptions, and a sense of impending doom. The narrative explores the limits of humanity's struggle against overwhelming odds and the consequences of delving into the occult to gain an edge in conflicts.

Overall, "The Worms of the Earth" is a compelling and dark tale that showcases Howard's talent for weaving together historical elements, supernatural elements, and heroic fantasy. It remains a classic within the genre and contributes to the enduring legacy of Bran Mak Morn as one of Howard's memorable characters.
