Ten Years ago...
Ten years ago The Mushroom Kingdom was in a break of defeat on a civil war with the Koppa Region and their leader King Bowser and once they had capture the kingdoms Princess and when news struck out that she was captured a spark was lit on two unlikely hero's
Two Brothers from New Dunk City
they went into The Mushroom Kingdom they battled their way through the Kingdom and the Koopa region, saved the Princess and defeated The Lizard King, and gave The Mushroom Kingdom a winning chance against Bowser and his army.
After his defeat Bowser looked for allies on Dinosaur Island and he founded the Yoshi's, Bowser had tried to get them to help him win for the civil war, but the Yoshi's said no and paid the ultimate price.
Bowser had imprisoned all the Yoshi's and took control of The Dinosaur Island, luckily only one Yoshi by the name of Archangel escaped and went to The Mushroom Kingdom to help his home and people.
The Mushroom Kingdom helped and defeated and captured Bowser, ultimately ending the war with his death...
or so we thought.
