She can surely forgive, but it won't be because of the erosion of time. The Sage hasn't done what needs to be done for her to forgive. She hates the first Sage, so she hates Soverick too. She hates Soverick, so her descendants also hate him. Lady Amari is one of her descendants. Lady Amari has been working with others that hate Soverick for one reason or another to undermine him.
Their efforts have all been fruitless so far. It all looks like childish attempts to her. She is sure that she can do better if she gets involved, and she also wants to get involved so that she can kill Soverick, but she won't. Her anger is still burning fresh, but it hasn't clouded her judgment. She can be rational despite her hatred.
