Errr...just guessing...Knights of The Round ?

What you think I am,
I'm not.--->don't really get this part here.I'll try to think more.
What I could be,
I cast behind,--->Err.Arthur comes out last,deson't he?
my link is with the golden,--->you can only get the materia with a golden chocobo.
yet no direct encounter made--->But there's no direct connection between a chocobo and 13 knights.

Of course there is a connection between a chocobo and Kotr, without a golden chocobo you cant get Kotr.
