Crystalis
You must save the world from evil magic by finding the four powerful swords that make up Crystalis. After the apocalypse, magic returns to Earth. A blessed group of wizards with good intentions have used their new magical powers to rebuild Earth, but an evil wizard named Dragonia has combined his supernatural powers with man-made technology to wreak havoc on the rebuilt Earth. Your task is to recover four mystical swords and combine them into the ultimate blade: the Sword of Crystalis. This legendary weapon is the only tool that can put an end to Dragonia's black reign.
Story
In the year 199X, mankind single-handedly caused civilization to collapse. To atone for their mistake, humans built a tower high up in the sky. They hoped that their hearts would no longer be ruled by demons. One hundred years later, the earth is ruled by monsters and people live in fear, but they still live together and dream of the return of peace. The basis for this hope is the legend of a savior that has been passed down from generation to generation.
