While Wizarding Britain was in the process of reinventing itself, a dark shade had just arrived in its only sanctuary, the forests of Albania. Mere days ago, Lord Voldemort had victory within his grasp. His Death Eaters had defeated Albus Dumbledore, the muggle loving fool, and his chief lieutenant Alastor Moody, whom had taken down many of his Death Eaters of the years.
Then suddenly, Potter and his tart had shown up and led a small band of Dumbledore's Order into battle. Potter and his tart then destroyed all of his dementors and summoned Merlin's Judgment. This was unheard of, even with all of his power; Lord Voldemort himself did not have power to summon this magic.
To add insult to injury, after being found guilty thanks to Merlin's Judgment, he was ripped from his body once again and forced to flee to the solitude of Albania. Besides being one of the places where Grindelwald had built his storehouses of dark artifacts, Albania also had very strong intersections of lay lines, similar to Hogwarts, but no where near as strong.
During the years before he returned to England to start his reign of terror, a young Tom Marvolo Riddle discovered Grindelwald's secret storehouse from his war in the 1940's. Within it was all sort of dark artifacts, books, amulets, and most important of them all, Gellert Grindelwald's pensieve.
For some reason, which remained unknown to the both Lord Voldemort and Tom Riddle even after exploring the storehouse extensively, Gellert had left a complete copy of all his memories in a pensieve so they would remain safe and by the look of some of the memories, Grindelwald had returned periodically to add more of his experiences.
Some of the memories were of Gellert in his earlier life when he met a younger Albus Dumbledore. Gellert had hated Dumbledore from the moment they met because Albus was a true student of the light while Gellert himself was a Master of Dark Magic. Gellert vowed to kill Dumbledore if it was the last thing he ever did.
After undergoing many of the rituals the Gellert had found or created to enhance his power, or extend his life, or many other terrible things, Tom Riddle slowly began to die away and was replaced by Lord Voldemort. After 15 years of learning and mastering everything within the storehouse, Lord Voldemort left the storehouse, stronger than even Grindelwald himself, and began to the foundations for his eventual rise to power.
The first foundation he laid was the building of his monolith. Using the incomplete notes from Gellert and his own brilliant mind, Lord Voldemort constructed this monolith to channel the natural power of the lay lines of the earth into a form of Dark Magic that Voldemort could use to strengthen him and sustain his powers.
There was however, a drawback to this monolith however. The monolith had no way to transfer its dark power to Voldemort without him physically touching it. Voldemort solved this by portkeying to the monolith weekly to recharge himself; while not perfect, it solved the issue at the time.
Like the first time he was banished from his body, he returned to Albania not to hide, but to live off of the power the monolith created. It was this magic that kept him sane and focused on conquering the world and killing Potter, but first he would live in the forests of Albania until one of his followers once again came to him. This time, instead of waiting 13 years, he knew that one of his servants would find him there shortly, for he had given specific instructions to Bellatrix and others to go to Albania if anything should happen to him.
Once his followers returned to him, they would begin the long process of first giving him a rudimentary body and then a fully operational resurrected body. This body would not have the same flaws that the one Wormtail created because no one, except for Crabbe and Goyle, were as bad of wizards as Wormtail had been. All of the ingredients were already in the storehouse waiting for him, all he needed to do was to wait until the moon was in the right position and the stars aligned; once that was done, Lord Voldemort would be reborn and this time he planned on staying that way.
He would first change the locations of his Horcruxes. Because of Merlin's Judgment, Potter probably knew where his Horcruxes were, if not what they were. With the enchantments placed around them, Voldemort knew no one would be able to get to them but him unless Potter sacrificed hundreds to obtain his precious prizes. He could not move them to any property owned by any of his Death Eaters or himself.
Though none of this mattered at the moment because Lord Voldemort was patient; he would plan out his strategy down to the smallest detail before risking another set back. This time, Dumbledore and Potter would die; with this thought, Voldemort possessed a snake and laid down for a night's sleep in his forest.
