The books inform the show heavily, but it is not anywhere near totally faithful.
Lanfear’s arc benefited from these shifts.
Although the show hasn’t covered it yet, Lews TherinTelamon ended up rejecting Lanfear for someone else.
Lanfear’s darker personality traits were enough to drive Lews away from her and toward Ilenya.
Lews married Ilenya, which infuriated Lanfear, naturally, given her possessive and controlling nature.
And yet, she is Machiavellian in her pursuit of power.
Lanfear’s lies finally convince Rand that she does not really have his best interests at heart.
Lanfear wants to rule with Lews inThe Wheel of Time, not look after Rand.
The Wheel of Time follows Moiraine, a member of the powerful all-female organization Aes Sedai, as she leads a perilous quest with five young individuals. Moiraine suspects one among them could be the prophesized reincarnation of a mighty figure destined to either save or doom humanity.
