Over the last feud between the 3 factions. The candy faction sided with the vampire queen, Marceline.
The fire kingdom was forced to fall back as the nightospheres forces attacked all that moves. I am general of the fire kingdom, Finn Mertins. As the fire kingdom fell back i looked down at the destruction. People squirming in pain, bodies everywhere. I made a break for it when i saw the vampire queen on the horizon.
She saw me.
At full speed i ran for it, but a vampire is too fast for me. She matched my speed perfectly and grabbed me.
I knew i couldnt escape from her dead grip on my throat. "That was just too easy." She was right.
3 hours later.
I was brought to my knees at the presence of princess bubblegum, the witch of the candy kingdom.
"What are they planning?" "I have no idea what the fu-" "I'll ask again, WHAT ARE THEY PLANNING."
...
"Take him to a cell, and make sure he doesnt escape."
I was forcibly thrown in a cell by the vampire queen.
"See ya later, wolf boy." The cell was disgusting. The only good thing was the beautiful full moon that sh-
Wait. Full moon?
I looked at it once again feeling rage course through my veins, the spirit of the hunt is here.
My eyes turned yellow like the sun and my teeth became like daggers.
Its beginning.
also since marceline wasnt burning during the battle and finn wasnt "turning"
just imagine clouds were covering the moon during the fight.
