Wemmbu is a Knight of Rage! (Derse Dreamer)
Wemmbu connects well with the rage aspect. At the beginning we see Wemmbu uncaringly sneak into the box that spoke commission to hold all his exploits, Wemmbu wanted to know the truth behind what Spoke was doing. He didn't care about keeping his contract or about appearing good. Which we see with all the times he kills players and takes down the people against him and his friends. Wemmbu does what he wants and if you're in his way, he’ll do his best to get rid of you.
The rage bound can tear down systems that, to them, are built on faulty premises- and Wemmbu tears down Zam’s kingdom after being betrayed. He lets emotions take control- out of revenge and seeing how the Kingdom is trying to control parts of the server, he tears it all away. Wemmbu holds his friends close, so when the people he trusts lie and betray him, it's only normal for him to get back at them at full force. Not to mention, Wemmbu often views less important players as npcs, people who are foolish.
He brings chaos to the people around him Wemmbu is dangerous and is seen as unpredictable. It's said that the rage-bound are- at their best original, revolutionary, and fearless and at worst cruel, uncompromising, and vicious. All things Wemmbu has shown throughout the Unstable SMP.
Despite how Wemmbu tries to play off his emotions and frame himself as someone who isn't bothered by loss and betrayal, he still views the world through a very Rage aspect-y way- through passion, intensity, and negative emotions. It's what leads him to want to become the strongest, what leads him to be so skeptical of others even though he wants to be able to place his trust in others.
Now to focus on the knight class, its an active class which works well with out active Wemmbu is in his goals lol. All known knights are known for concealing their innermost selves in part to address a flaw/insecurity. Wemmbu wants to prove that he is powerful- useful even, the rage tendency to doubt himself makes itself known. He’s afraid to get closer to others and how people will see him as weak if he does get close, so he acts like he doesn't care and convinces himself that he shouldn't care. When he pushes himself to become better, stronger, just who is he trying to prove this to? In the end, this power was just a cage he would have to free himself from, a challenge for him to confront head on.
Whatever the case, Wemmbu doesn't focus on these emotions, he focuses on the adrenaline he gets from his battles. Choosing to put his exploitative class to work, Wemmbu uses rage in a way that can frustrate others through combat and can protect people with it.
As a Knight of Rage, the session would have a lack of rage, and Wemmbu would sever the role of pushing goals forward with intensity and unpredictability. Along with assisting the space player Spoke with the frogs!
