Valar ‘Angelic Powers’ is the name given to those divinities created by the One before creation itself. They dwelled in Middle-Earth as guardians of the world. The Valar is discussed a lot in the Quenta Silmarillion. When Melkor returned to Middle-Earth his power grew and the Valar were defeated for the first time. It took them a long time to try and defeat him again.
Vanyar ‘Fair-elves’ is the name given to the first kindred of the Eldar. In other words, the ‘Highest’ of all High-elves were called this. They were led by Ingwë, who was their first and only king. They left Middle-Earth and only returned one time. They returned as warriors of the host of Valinor to wreak final justice on Melkor.
