Moraine "lies" in book 1 ch18
On my 5th? 6th? Reread.
Book 1 Chapter 18, when the party is just infront of the walls of Shadar Logoth attempting to lose the trollocs chasing them, Moraine gets the group together and waves her staff over their heads and then has a wind blow off to the west to distribute their scent and tracks.
Egwene remarks that her staff must be very powerful, and Moraine replies
> "I have told you child, things do not have power. The one power comes from the true source and only a living mind can wield it."
We know about standing weaves from the age of legends, of terangreal, including ones which don't need the user to know how to channel, for example the twisted stone ring egwene uses to enter tel'aran'rhiod. The twisted stone doorways. The ways.
I know early book weirdness, and that it's not really a lie, perhaps she can be interpreted to mean something more specific, e.g. objects got their power from someone originally. But to be honest, that's what Egwene is saying too - she thinks it's an object which has a lot of power in it and can do a lot of things. For fun, I'm interested in how many example there are where she has first hand knowledge of "things which have power" at this point despite what she says.
