After 2 weeks, Eclipsa getting better and she could rule Mewni again, even if sometimes she had the vision that she feared the most, but Luna always calming her mother, support her as time flew by, her psychiatric problem dissapear. Lady Cross suggest that not giving her hard problems and stressful work and Eclipsa will be ok. But the war didn't stop. The Spiderbites keep attacking and Eclipsa always handled it but she was very stressful. One day, the MHC decided to go to the Spiderbite Kingdom to beg King Spiderbite, King Shastican, to stop the war

"Please your majesty, we need to stop this war"
"You can, but I have 1 condition"
"What is it?"
"I want to be King Of Mewni"
"WHAT?! But that means, you want to marry-"
"Yes, Queen Eclipsa Butterfly"
"But, she wouldn't want to. Since King Edric is killed, especially...."
"Ask her first and if she agree, I'll end the war against us"
"We understand. Thank you for giving us the chance to stop this war"
"Go"

"WHAT?! But I-"
"Think about this Eclipsa. We could end the war"
"But.... He was the one who killed Edric. I can't do that"
"We didn't force you to marry him, but think about that. This war didn't end since Edric died. And if you died, Luna had to burden this, do you want her to suffer?"
"I.... I'll do it. For the good of the kingdom and Luna"
"Thank you. He'll be here in 3 days"
"I understand"

"Luna, dear. Can I come in?"
"Ow yes mom"
"Luna, I want to tell you something. And you have to accept this OK"
"What is it mom?"
"You're going to meet your stepfather 3 days later"
"What?! Mom, who? I think-"
"I know sweety, I have to do this. He'll end the Spiderbite War if I do this"
"So you mean that, you're going to marry Dad's murder?!"
"Dear, I know how it feels like but for the safe of the kingdom.... I must do this. And I do this for you. If you take the throne, I don't want to see you face this war"
"Hmm, I'll do anything for the kingdom's safe"
"Thank you dear"

(Time skip, 3 days later)

"Your highness, King Shastican from the Spiderbite Kingdom"
"Your royal grace, Queen Eclipsa Butterfly, the Queen Of Mewni"

The two royals took a bow and going towards the throne room. In there, sit the MHC and Princess Luna Butterfly

"Queen Eclipsa, at last we've meet"
"It's an honor to meet you King Shastican. I suspect you to sign this peace treat to end the war between us" the guard then step into the room and bring a scroll
"Of course" he said while Shastican sign the scroll
"Now about that, the wedding should be prepared now. I expect everything should done 1 week later"
"Yes, I could assure you that everything will be prepared"
"Mom, can I-"

Eclipsa was about to speak when someone cut her

"Not now Princess, the adults are having conversation and it's rude to cut someone talking"
"No, no, no. It's OK"
"Princess Luna, as the princess of Mewni, you must follow the rules of Mewmanity and I expect you to memorize them all 4 days later"
"What?! Are you-"
"Luna, please, you can go now"

"She didn't mean to do that your majesty, I'm truly sorry if you're angry at her. She's just 8 years old" said Eclipse
"No problem. But at least, she act like a proper princess"

Proper princess?! So you said my daughter is not a perfect princess?! said Eclipsa in mind

"Well, then, I guess, I'll be on my way then. Goddbye your highness"
"You too King Shastican"

"He's too mean and cruel for someone like you mom"
"I think so too Dear, but what can I do? If I didn't do this, then the war would continue"
"But mom, what if you...."
"I won't. I'm sure he wouldn't stress me out"
"OK mommy"

(Timeskip, 3 days later)

Everything had been prepared. Luna, who's not agreeing to do this, was very furious. She already memorized every Mewmanity rules and this afternoon, Shastican will test her. She almost ruined her white dress because of this

"Luna, dear, are you done?" Said a voice from outside
"Yes mom, come in please"

Eclipsa is wearing her usual golden crown, white dress, with black high hells

"Mom, you look beautiful"
"Thanks dear. Come on, let's go"
"Mom, are you sure, you wanna do this?"
"Yes, it's not love that's important right now. It's for the good of the kingdom"
"Alright, I understand"
"Come on now, let's go OK"
"OK"

(TimeSkip) I found it boring to watch the married because of that stupid idiot king

After a few days, Eclipsa found it rather upset with her decision. Shastican isn't like Edric or what she had expected. He's rude, mean, and almost hurt her the last few days. Eclipsa showed no expression to Luna and Luna thought that her mother is OK, until she heard a vase break from her mother's room. Her step father get out from the room with furious expression as he walk Angrily toward the hallway. Luna got into the room and found her mother bleeding with a big scars in one of her spade cheekmark

"Mom, are you OK? What happened?"
"...."
"Mom!"
"...."
"Hekapoo, Rhombulous, Omni!"
"What happened?" Ask Hekapoo quickly rushed through the hallway
"I... I don't know. I was just walking toward my bedroom when I heard a vase falling and when my step father get out from the room, I found mother like this"
"Call Lady Cross here now" order Omnitraxus
"Of course" Hekapoo said as she walk towards the mirror

"Queen Eclipsa is in coma circumstance"
"WHAT?! How?" Shout Hekapoo in disbelief
"Maybe because of scared too much, stress, or the scars. Who did that though?" Ask Lady Cross
"Well, my step father just went out from mom's room with furious look.... So it could be him who hurt my mother. He's just a evil, mean, and heartless mewman that doesn't care about-"
"Luna, I hate to interrupt you but, please don't speak like that. Your step father is outside. He could hear you anytime now"
"Yes and I definitely hear it" said someone who just opening the door of Eclipsa's room
"K... King Shastican?! We truly sorry of what Princess Luna had said, we-"
"SHUT UP YOUR MOUTH OR I'LL DO SOMETHING EVEN MORE ROUGH THAN THAT!!!" Snapped Shastican
"We truly sorry" said the MHC as they stand kneel in front of him
"Fine, I'll forgive you this time. But the next time you speak like that. I'll have your mother killed" he treated
"O... Of course"

Luna remains silence. Who did he think who he was? He didn't have magic and want to threaten the most powerful Queens Of Mewni?! Is he crazy?! But Luna still afraid of him. The MHC stayed silence too because afraid that if he's gonna bring the war again
