The idea behind the following story kinda of inspired by a story once told by Joey(Jonouchi) about Gearfried the Iron Knight, and made me think about how each and every Yu-gi-oh card potentially has a large history behind them beyond the anime or the mythology that many of them were inspired by, so the idea is more of something that could be told around a campfire appose to out of a book.
So hopefully you enjoy this little tale and the more to come
Also I suppose I should mention I don't own any of the characters
A long time ago in ancient times, the land was barren with little to no life beyond the twisted remains of a once great society and a city protected with magic, The Magical Citadel of Endymion, in this fortress city; there were two brothers, who were apprentices of magic; as most brothers are, they were constantly at odd and they used their rivalry to become stronger. As years went by they increased in skill and power but, as they grew older their paths of magic diverged and given focus by their masters. One was taught to follow Black magic, focusing on power and strength, the other followed White magic to heal and give strength but, it was not meant to last. The White Magician begin to hate his carved out path and resented his brother, it wasn't long after that he made his feelings known by attempting to strike down his brother, as an attempt to prove his strength. He failed to defeat his brother and their master soon discovered the White Magician's deceit, and as an act of punishment he banished him from his home and forced him to wander in the barbaric wasteland for the rest his life. Although he left with little resistance, he vowed he would return.
3 years have passed since that day and the Dark Magician had grown in strength and even took on and apprentice of his own and the Citadel seemed to be at peace, but unfortunately it seemed it was not meant to last, as the old mentor of the Dark Magician, the Dark Sage had a vision predicting that a great and powerful spell caster would attack and destroy the village but, the vision was unclear of who or what it could be but, as the predicted day grew closer, the residents grew anxious and quickly pointed to the possibility of the White Magician's return.
As dawn broke, it was said that an overwhelming force crept over the desert's horizon, with only mere hours remaining until there foreseen end; they made certain that they would not go quietly. Each and every able magical soldier stood at the gates, beyond the magical barrier, waiting. The Dark Magician stood on the front line believing that today was the day he may need to slay his own brother in the name of his home, he stared at the rising sun as what could only be described as a force of destruction inched ever closer. Finally it was clear what was coming, an army. An army of Dragons.
