Z'Skayr, Dr. Viktor, and Crujo were face-to-face with a beautiful sorceress. 

Charmcaster (An old enemy of Ben! She is a sorceress and the ruler of Ledgerdomain! She was the niece of a powerful sorcerer named Hex and had a rivalry with Gwen! Despite all of her cruel ways in the past, she has developed a moral compass and has become a better person, who is desperate to keep her domain safe! Pretty cute and nice when she can be! Voiced by Kari Wahlgren!) 

Z'Skayr: Who are you? 

Charmcaster: I'm here to reclaim the Alpha Run! 

Z'Skayr: My apologies, dear child, I have no idea to what you are referring. 

Charmcaster: It is an object as old as time itself, through which all magic flows. It is the keeper of the true name o my realm and a source of ultimate power, and it is mine! 

Z'Skayr: Oh, this Apha Rune? 

He revealed a rune that was in his chest. 

Z'Skayr: I'm not quite ready to give it up just yet. 

Charmcaster: So be it, I am Charmcaster, daughter of Spellbinder, conqueror of Addwaitya, ruler of Ledgerdomain, and I will not be deni- 

Z'Skayr teleported her out of the castle just as soon as Charmcaster was about to try to attack him! 

Z'Skayr: Back to work! 

At the Lovely Duck... 

Ben: AAAAAAAAAAAAAAAAAAAAAGH! 

Charmcaster appeared before Ben, and he had purple pimples on his face!

Ben: Hey, not cool! Some places are off limits to girls! Even evil girls! 

Charmcaster: Huh? What am I doing? 

Ben turned into Swampfire! 

Swampfire: Charmcaster, I'm about to teach you how to knock! 

She began talking to her bag. 

Charmcaster: Him? That's Ben Tennyson. Yes, I'm sure. Yeah, he has looked better. 

Swampfire: Wait ... why are you out of Ledgerdomain? 

Charmcaster was looking around. 

Charmcaster: Yeah, I think this is a loofah. 

Swampfire: And why do you seem much more cuckoo than usual? 

He turned back to normal as you and Rook came in. 

(Y/N): Hey Ben, we heard you scream, what is- 

Ben: HEY! OCPUADO! Seriously, does no one respect the sanctity of the bathroom? 

Charmcaster: No, I didn't zap us here, Z'Skayr did. Providence? No, I don't think so. 

She then noticed you two. 

Charmcaster: Them? I don't know. But that one looks very cute. 

(Y/N): (blushing) H-Huh? 

Charmcaster: Yes, I think he's cuter than you! Now shut it! 

Rook: Great amber ogia! Charmcaster has put a spell on Ben! 

(Y/N): I doubt it; she doesn't seem that bad from what Gwen described. 

Ben: This is just a- Wait, how do you two know about Charmcaster? 

(Y/N) and Rook: Gwen. 

Ben: When did you get the time to talk to Gwen? 

(Y/N): Well,  it was more like a video call regarding all the enemies you faced as a kid. She talked on and on about Charmcaster, and they both had an intense rivalry going on, and she did a lot of bad things. But ... I expected an evil bitch, not this cutie! 

Ben: Right. 

Charmcaster: That's a rubber ducky. Hahahaha. No, that won't help. Yeah, I think so. 

Rook: Miss, you'll have to come with us. 

Charmcaster: Great. Let's get going. We don't have much time! 

She left the bathroom. 

Ben: Guys, look, she may be acting like a few sandwiches shy of a picnic, but I'm not buying it. She's not exactly trustworthy. 

(Y/N): Yeah, Gwen mentioned that. 

Ben: Right. 

Charmcaster: yes, I know, but he's being Ben. No, he's still arrogant. 

Ben: HEY! 

Charmcaster: Hey, we both want Z'Skayr, so we should work together towards a mutual goal. Why can't you see the logic in that? 

Ben: First of all, you're talking to your purse. Second, you've tried to destroy me on several occasions. 

Charmcaster: Oh no, I'm pretty sure he didn't mean that as an insult to you. 

Later... 

(Y/N): Guys, well ... this is Charmcaster. 

Rad: W-Wow. 

Ruby: She's kind of cute. 

Blake: Isn't she an old enemy of Ben?

(Y/N): Yeah, sort o- 

Hobble: (heart eyes) Hello, gorgeous! Welcome aboard the Lovely Duck. 

Charmcaster: Yes, I know every second counts. So, you'd rather stay cooped up, surrounded by people who clearly don't want you here, when Zs'skayr is within your reach and I can help you defeat him? Now who is the irrational one? Either way, are you coming with me to defeat Z'Skayr once and for all or what? 

(Y/N): Okay! 

Ben: (Y/N), get your mind right, she can't be trusted! 

(Y/N): She can be of good use! Anyone else want to come and- 

Hobble: ME! 

Ben: Uh, I think we're good, Hobble. 

Charmcaster: No, the stumpy one amuses me. Besides, we need bait. 

Yang: Hey, good idea. 

Hobble: WHAT?! 

(Y/N): Let's just go. 

You all went outside as the monsters were freaked out by Ben's face. 

(Y/N): Hey, stop staring, guys! 

Monsters: Sorry. 

(Y/N): Thank you.
