Undead Invasion

After Yag Zhu  was freed from his Upside Down Pyramid prison, he set about gathering the magic needed for a ritual powerful enough to ressurect all the corpses on the NeoCap . He succeeded by employing the Corpid Crystal . He got his army and began conquering the NeoCap . He took New Anfang , Capital City Moss Point , Upper Minespa , Lower Minespa , and came all the way to Kun Badur .
His ritual had unintended effects, including the resurrected Crimm Baphra , another villain, that was immune to being controlled by the Corpid Crystal , and began his own plans of conquest.
The battle at Kun Badur was won by the heroes, and the forces of Yag Zhu were eventually driven back all the way to Capital City Moss Point  and to Castle Yag Zhu , which was in the Deadlands. An enormous army of heroes and wizards came together to destroy him, and they blasted the castle with so much power it created the Swath .
