Who are the two blue wizards?

The two blue wizards, known as Alatar and Pallando, are lesser-known characters from J.R.R. Tolkien's legendarium. They are part of the order of Istari, sent to Middle-earth by the Valar to aid in the fight against Sauron. Unlike the more prominent wizards like Gandalf and Saruman, their specific roles and fates are largely left unexplored in Tolkien's writings. Some interpretations suggest they went into the east of Middle-earth to combat dark forces, but details remain vague.
