The cannon was first created by Seklos in order to kill Gaylen after his lust for power began to threaten the universe. Seklos then placed her own life core in it and destroyed Gaylen.
Many thousands of years later, General Morando acquired Gaylen's Core from Trollmaket and integrated it with his life core to gain Gaylen's power. The royal heirs, Aja and Krel Tarron, created a replica of the cannon and intended to power it with their own life cores to put an end to Morando. However, the cores were supplied by a newly-regenerated King Fialkov and Queen Coranda, who gave their lives to power it.
It is a giant, modern gun with several barrels and a general colour scheme of grey interspersed with yellow. It has a small cavity used for containing cores.
