Version One
The Gatekeepers Blade called The Gatesmasher was invented by a dream named Togus. He was passed the erratic notes that were written by the Lucidity DreamWright who created the FateSenders Blade called the Fateslayer. He carefully sculpted his Blade, replacing ingredients with willpower and Melee. Thus, with these ingredients, the Gatesmasher formed.
Version Two
We probably will never know name of Great dreamer which created it. Histories remember only the name of the Great GateKeeper which added this powerful art to the Major GateKeepers Arts it was Askold apprentice of Retvizan. He also researched this art and upgrade it and now this art allows to teleport in each (marked before) place, not only into house, as it was at first. Now history will never forget name of this Great Dreamer, created such a powerful art. His name will stay with us forever, as his creation.
