New beginnings

I have walked for years, I have seen

I believe in my eyes, for my eyes tell me illusions

I stride for years, I observe

A new beginning, with new explorers

I have learned, I have love

Those that hold their fate, their probability

A new challenge has come, you have no idea what is to come

And through this, I am the object of triumph; you may obtain this

I am a kind of fabric, though incomplete

My being lush, green, beautiful and majestic, though terrible and fatal to all

OK ALL! So here's an updated riddle cause after much deliberation and getting some pretty solid feedback elsewhere, perhaps this will help!

    -If you have triumphed over your foes, the crowds will name you this; one deserving of such words as winner and glorious

    -I am a cut above the rest, a fabric worn by kings; my quality is better if I’m crushed, unlike most other things.

    -Am I a tree of evergreen? A plant of poison leaves? Or am I the place you put a key, at the seam the tailor weaves?

And one more extra big hint, this is a name, a first, middle, a last, AND that the second line is only the first half of the word, a word which rhymes with a musical instrument found in a church! Good Luck!
