When was it that Moraine said that Rand's friends were not mentioned in the KC?

ok... elyas is a wolfbrother. that much is clear. he was a warder, to some aes sedi and discovered the talent late. (or atleast later than perin.) anyway he was thought to be a shadowspawn, or darkfriend by some of the warders so they tried to kill him. he killed one and fled to the balck hills. where he met hopper and the others.

I believe it was tDR, when speaking to Perrin about his wolf dreams.
