One day Jestar was walking through the desert looking for a ancient temple to find a blacksmith called Xero so he could make a heart locket prison. Then he could trap anyone who tried to stop him from taking over the realm.
After a hour of searching and getting prickled by green, prickly cacti, he found a small rock shaped like a cog. Jestar brushed away all of the sand and it revealed the temple where Xero lived! When Jestar went into the temple, he heard someone playing the violin. 2 months later he got the heart locket and his first soul and made a clone called Medusa who could summon anything out of lightning.
