“What are you doing to me?!”

The madman, tinged with the darkness of insanity, gazed into the eyes of
his brother with a grin stretched across his frightening face. “I'm
cleansing you of your faults.” Steve announced as Alvin was being
burned at the stake. “You will never hurt anyone again, not as you
have hurt me,” Steve rambled on, “You put me in this living Hell,
with no way out. You stuck me in this world of monsters, alone and
afraid as you wasted away in the comfort of others. You will learn
of your mistake.” Steve's brother screamed for hours until his
ashes vanished into thin air.

The madman's brother awoke with no memory excluding that of Steve's
torture. Rage boiled in his head as he sat up in the endless field;
the place he had trapped his brother in for years on end. He walked
through the grass, concocting his plan for revenge.

Years passed in the scourge's venture to escape this lost world. He had
reached a conclusion that, when the sound barrier was broken, a
wormhole would be formed creating a path between his realm and his
home. For a time too long to be recorded, Alvin had continued to
build into the sky, finally reaching the point that would allow him
to travel inter dimensionally. Gazing down and seeing nothing but a
thick fog at the bottom of his pillar of wood, he leapt and passed
through the path to his homeworld.

The scourge, seeking revenge, was more than ready to fight in the final
battle between kin. Upon arrival at the steps of Steve's home, his
marred face formed a deformed smile, and the duel commenced.

(Basically, Steve, a crazed lunatic, burns his brother into nothing because he's
the one who stuck him in the world of Minecraft (Steve had escaped
and gotten into the real world, so he's getting revenge). Steve's
brother, the scourge, somehow forms back and seeks revenge on his
brother who had taken revenge on him, so it's basically revenge on
revenge... I guess. He creates a portal to the real world which Steve
is in, finding his house and fighting in a boss battle.)
