"All things return to the VOID."
The two most powerful forces in the universe are that of Creation, to begin from nothing, and Destruction, to return to nothing.
Master Masq is the Avatar of the the VOID, a nigh omnipotent force determined to end all things everywhere. He is THE god of endings. He has erased countless universes and is remorseless in that pursuit.
Seemingly unmoved by the struggles of "The Creation", the totality of reality as we understand it, Master Masq is infinitely patient and relentless.
The most powerful beings who destroy of their own will, simply serve the Void and Master Masq informs them of this as the need arises. But make no mistake, Masq does not need them and if they turn their talents on him they too will be returned to nothing.
Only the Principle Guardians of Creation and those scant few chosen, the "Gold" and "Silver", can fend off the Void's direct advances. But even this minor obstacle does not concern a being to whom time is his ally and their deadliest foe.
*Master Masq is a father, whose son, Elgin Souji was used in an attempt to kill Elzabeth M'roln and use his unstoppable might to bring down the Great Wide Universe (GWU). Elgin however, felt as if he was trying to kill his twin sister, and chose to defy Master Masq, never knowing that the being was his father. Masq can not bring himself to kill his son and so has only issued the decree that he is to be killed when found.
Elgin lives between universes in the Estate of Sorn with Lord Rhodin, the current Leader of the Principled Guardians of Creation.
