Though to be fair, if there was a change of direction, that would be one of the signs :-)
True. 
Wulfram, forgive me, I didn't see your post till I posted this and now I can't properly quote you. She might believe it, but that doesn't necessarily mean it's true. Again, without reading the Grimoire ourselves there's no real way to know. That, and if you go by Flemeth's take and Yavanna's from what I can extrapolate from the Wikia, it isn't necessarily what she interpreted it as. Flemeth says you cannot possess the unwilling. And while I can't honestly say if this is true about Yavanna, the Flemeth entry on the wikia suggests that according to Yavana the whole ordeal is a gift. http://dragonage.wik...om/wiki/Flemeth
Again though, take that as a grain of salt. I haven't read the Silent Grove and can't confirm it. Just throwing it out there in case someone here can shed light on it. Especially if it isn't true.
There's shards of the truth in what all of them say, I'd wager. But each is tinged with their own biases and secrets.
