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.
She knows enough about the first Sage to know that she won't succeed if she tries anything. There are other reasons why acting personally is a bad idea. The first Sage would have surely expected things like sabotage, so it won't work. Rationality dictates that she stay away from this particular competition. It is not an overreaction. It is a decision based on her vast knowledge of the first Sage, the Void Universe, Soverick, and most importantly, the entity that calls itself Legion.
The first Sage never loses. Any person that deals with him is at great risk of losing everything they own, but the Sage never loses. An investment is risking your resources for a larger return. You can lose your investment if it fails. The first Sage might fail, but he doesn't lose anything. At worst, he might draw even without gaining anything, but he has never ever lost his investment.
She has never been good with plans and schemes. That's more of the first Sage's talent. She is more of an investigator and researcher. Her set of skills won't help her to win a confrontation with the first Sage. She has to admit that the first Sage is very competent, and she hates him for it.
The first Sage's competence makes her hate him. It also makes her fear him. Her hatred for him bleeds into her hatred for Soverick. She knows that Soverick was created by the schemes of the Sage for his purpose, so she hates him. That means she can't move against Soverick directly without drawing the ire of the first Sage. So she has to be content with the effort of her bloodline descendants.
The bloodline of the sage care for the plane, while her own bloodline hates the child of the plane and covets the title too. Soverick already had enemies before he became the child of the plane. She is not able to deal with Soverick directly, but her descendants can.
It is frustrating that she can't act herself, but it is also good that her descendants are the ones making trouble. It will keep her from taking risks and putting herself in danger. This entire competition might be a trap. She certainly doesn't want to fall into a trap set by the first Sage.
That serpentine world god that the first Sage is toying with might try to eliminate the Sage's greatest hope in one way or the other. Or other world gods might try to get to Soverick now that he is out of the realm tree. Those are actions that she will advise against with good intentions. I think you should take a look at
It is because this entire competition might be a farce to catch a very big fish. World gods are very big fishes if you know how to catch them. And it is just like the first Sage to be always prepared to catch a big fish. If the Sage could bait Soverick, then Soverick can surely be a bait to others too.
So Rationality and logic dictate that she keeps her display of anger to just fuming and kicking up a fuss. She is rational, so she will do just that. This tantrum of hers is not nearly enough for her. But she can only remain content with that and the knowledge that the child of the plane in the competition is not a battle sage monkey.
The child of the plane just looks like a battle sage monkey. It isn't a battle sage monkey. It is some entity known as Legion. This entity is masquerading as Soverick. She doesn't know a lot about this Legion because something is blocking her view of it every time she looks at it. The only thing she can see past the Universal artifact in Soverick's soul is Cosmic energy. A lot of cosmic energy can blind even a world god.
The realm lord has many Universal artifacts that she knows about. She knows that he gained most of them by breaking the rules of the Void universe. She doesn't know how he got the one called a system. That one has been with him since he was born.
Those Universal artifacts are very powerful. Only the best of the best in the void universe have one. She has one, but she isn't going to mess with the realm lord. She knows what she had to do to gain that one. That's why she won't mess with others with a universal artifact. At least she won't mess with someone that has multiple universal artifacts.
The realm lord has Universal artifacts, but he doesn't have access to cosmic energy. Meanwhile, Legion has cosmic energy and a universal artifact. She is sure of one universal artifact, but there can be more. She doesn't know because of all the cosmic energy that Legion has.
She wouldn't mess with the realm lord, so there's no way she would mess with this Legion. Cosmic energy is the root of POWER and AUTHORITY in the void universe. Cosmic energy is used to turn the ephemeral comprehension of laws into tangible Authority in the void universe. That tangible Authority is converted into a concept. The property of concepts being indestructible because of cosmic energy is what makes Origin gods immortal.
