Maia are angelic beings who are lesser than the Valar (the gods of Arda). They are powerful and wise, but not as mighty as the Valar.
Here's where you can find information about Maia:
* The Silmarillion: This book provides the primary source of information on the Maia. It covers their creation, their roles in the shaping of Arda, and their involvement in the First Age.
* Unfinished Tales: This book contains additional information about the Maia, including some biographical sketches of individual Maia.
* The History of Middle-earth: This series of books, edited by Christopher Tolkien, includes drafts and notes that shed light on the development of Tolkien's mythology.
Some prominent Maia include:
* Saruman: A Maia who served the Valar but became corrupted and served Sauron.
* Radagast the Brown: A Maia who served the Valar as a protector of animals and plants.
* Melian the Maia: A Maia who fell in love with an elf and became the Queen of Doriath.
* The Balrogs: Maia corrupted by Morgoth.
While Maia are not directly explained in The Lord of the Rings, their influence is present throughout the story. For instance, the actions of Saruman and the threat posed by the Balrogs highlight their power and impact on the world.
