In J. R. R. Tolkien's legendarium, the Elves are a sundered (divided) people. They awoke at Cuiviénen on the continent of Middle-earth (see: Awakening of the Elves), where they were divided into three tribes: Minyar (the Firsts), Tatyar (the Seconds) and Nelyar (the Thirds). After some time, they were summoned by Oromë to live with the Valar in Aman. That summoning and the Great Journey that followed split the Elves into two main groups (and many minor ones), which were never fully reunited.
The name Quendi refers to all elves.
The Avari are Those who Refused the Summoning of Oromë, or simply The Unwilling. Half of the Avari came from the largest tribe, the Nelyar, but most of the Nelyar went on the journey. Half of the Tatyar remained as well.
After the Separation the Avari became divided even more than the Eldar, though little of their history became known to the Elves and Men of the West of Middle-earth. At least six kindreds existed, and they continued to call themselves 'Quendi', considering those who went away as deserters. Some of these tribes later also journeyed westward, intermingling with the Nandor, and a few even reached Beleriand, though usually remaining in unfriendly relationship with the Sindar.
Life
Life is about evolving and growing
Elevating
Constant growth
Like green leaves
I dedicate this to the children
Mama told me a wise man leads and never takes orders to follow
And what's done right here in the here and now, always affects tomorrow
It's like, cause and effect, simple mathematics like 1 plus 1 makes 2
See the bed that we make, that's where we got to lay, so be wise of the path we choose
And keep growing
Keep growing (Keep on growing, yeah)
Keep growing (Oh, keep growing, growing)
Keep growing (Keep on growing, keep on growing)
Keep growing (Like)
Like green leaves
To have it you got to see it, to talk it you got to be it
There's no ifs, no ands or buts
If you claim it you can attain it, what was made shall be, and that's the law of the universe
(That's the universal law)
Shine a light, use insight and remember your precious gift
Take the good with the bad, the tears with the laughs and always be positive
And keep growing
Keep growing (Oh, keep growing)
Keep growing (Keep on keepin on)
Keep growing (Keep on growing)
Keep growing
