Blue Wizards

The Blue Wizards were two Wizards sent to contest the will of Sauron in the furthest regions of Middle-earth. They were known as Allatar and Pallando and were part of the Order of the Istari.
It is told that aside from Saruman, Gandalf, and Radagast, there were others of the Istari who went into the east of Middle-earth, and do not come into these tales. The two Wizards were sent to the East whose names were "Alatar" and "Pallando". Alatar was a Maia of the Vala Oromë who chose him to go to Middle-earth. Alatar asked his friend Pallando to join him on his mission. The time that the Blue Wizards arrived in Middle-earth is uncertain. Tolkien wrote that the five Istari came to Middle-earth together in TA 1000. However, in The Peoples of Middle-earth, they are said to have arrived in the Second Age, around the year SA 1600, the time of the forging of the One Ring. Their mission was directed at weakening Sauron's forces in the eastern and southern parts of Middle-earth, whereas the other Istari were focused on the west.
