Chapter 4

Finn, Jake, Ellie, and Flame Princess were waiting for signs of Necromorph activity.

Jake: So, "Ellie"', how come you changed your name to Princess Bubblegum?

Ellie: Before the mushroom war, there were these fanatics called Unitologists. They worshipped the Markers that spawned the Necromorphs. They even try to create more.

Finn: How do you worship something that kills people?

Ellie: Like I said. Fanatics. When enough of the planet's population has been converted into a necromorph population, all of the Markers, natural and built, merge the Necromorphs and turn the host planet into a Brethren moon.

Flame Princess: Brethren what?

Ellie: Brethren moons. They're created through an event holy to the Unitologists, called Convergence. They believe that they were meant to be assimilated into one.

Finn: You still haven't told us why you changed your name.

Ellie: After the mushroom war, I had to hide my identity, to keep safe from anyone who could be a possible Unitologist.

They soon received a distress signal from the Ice kingdom.

Ice King: Princess Bubblegum! I need help here! Strange creatures are attacking us! Help!

Princess Bubblegum: On our way.

The transmission cut off.

Princess Bubblegum: To keep my identity safe, you're to keep referring to me as Princess Bubblegum. Go that?

Finn: Sure.

Jake: No problem.

Flame Princess: Whatever you say.

Princess Bubblegum: Oh, and you guys are gonna love this. These suits fly.

Finn: Awesome.

They slid their helmets on as they flew over to Ice Kingdom. When they arrived, Necromorph ice creatures were swarming and killing the penguins, turning them into more Necromorphs. There were infectors, stalkers, slashers, and a large brute to head off the attack.

Finn: Uh, PB?

Princess Bubblegum: Yeah?

Finn: If Brethren moons lead the Necromorphs, where are they?

Princess Bubblegum: When me and my human friend, Isaac Clarke, were battling the Necromorphs, he sacrificed himself to destroy the only Brethren moon, and to stop the Necromorphs. I thought it was the only Brethren moon, but I fear I was wrong.

Finn: I actually had a weird dream. I just heard a voice that said, "We are coming. We are hungry".

Princess Bubblegum: That was the Brethren Moon!

Jake: Uh, guys. We still have a kingdom to save.

Finn: Right, let's go.

They landed on the base of the mountain and drew their weapons. Finn used his Plasma Cutter, Jake used his Ripper, Princess Bubblegum used her Plasma Cutter, and Flame Princess just used her fire. Finn and Princess Bubblegum attacked the slashers.

Princess Bubblegum: Come on you ugly freaks! Bring it on!

Bubblegum used her Plasma Cutter to cut off the blades of two of the slashers. One charged behind her and was stasised by Finn. He cut off both of the slasher's arms and used his kinesis to launch a slasher blade into another slasher.

Jake: Nice!

Flame Princess: We got more incoming!

A group of stalkers appeared. One hid behind an ice block, making a sound that distracted Jake and Flame Princess. When they approached, a stalker charged in from the other side. Flame Princess lit it on fire and roasted it.

Flame Princess: Not today.

A brute soon came out and tried to attack them.

Princess Bubblegum: Be careful guys. These things are tough. You got to cut them up from the back.

Finn: I got this.

Finn tried to stasis the brute.

Requires additional power.

Finn: What?! PB! You could have told me that these things need charge!

Princess Bubblegum: I still have stasis.

She stasised the brute, and Jake cut it up from the back. When it was dying, it let out a massive roar as hundreds of Necromorphs surrounded the group.

Jake: There's too many of them.

Finn: Oh, Glob!

Suddenly, something flashed past all the Necromorphs multiple times. They suddenly began to fall into pieces. The flash soon slowed down, revealing herself to be...

Finn: Marceline!

Marceline: Sup' y'all?

Princess Bubblegum: Your timing could not be better. Thanks for the help.

Marceline: Anytime. I'll got get Ice King.

She flew into the mountain and grabbed the Ice King and flew out.

Ice King: Is it over? Are they gone?

Marceline: Yep. They're gone.

Ice King: Phew. I thought I was a goner.

Finn: Let's get back to the Candy Kingdom.
