(A Beta concept)
He look upon the sea from the small boat his in. With wand in hand, he cast the only spell that can help calm the person that's making sure that they don't capsize considering how harsh the weather had become.
' Expectro Pertronum'
A ghostly silver Phoenix shoot out and fly around them, the aourer that were maning the boat took a deep calming breath and wave his own wand forcing the sea water to still. Flicker his wand again, the boat push fowerd unheeded. Seeing this, the old wizard nodded and his wand slowly moving the silver Phoenix around them.
"Thank you, Headmaster Dumbledore. Usually my partner will be with me, but he suddenly had family matter and I am sorry for bothering you to assist me."
Dumbledore just wave his free hand nonchalantly dismissing the comment as he flick his wand high and the silver Phoenix shoot up banishing a few dementos that had gotten to close. The aourer just chuckle nervously seeing this, and commented.
"Well, considering what you came here for. I am actually surprised that I to didn't run away."
"And you didn't. That is enough for me to believe that you won't intentionally make me wet and what am I would do if there's no guide left for me." The aourer just chuckle nervously again. He look around and notice the rigid and sharp stone around them and know that they are near.
He twirl his wand around and cast the usual spell to prepare them to dock the small boat, as they're reaching the shores. He made sure the boat was steady for the headmaster.
" I'll be going now, headmaster. The team on duty had been notified for your visit and where you would be. And be careful headmaster." The aourer bowed and left.
Dumbledore looked at the man, watching him struggle to maneuver the boat from the rocks headed to the open sea. shaking his head, he turn facing the opposite direction from the prison and walk towards a more isolated place on the island.
As he walk near the location, Dumbledore start his preparation. Taking out a vile containing white clear liquid, he drink it in one shot. Flicking his wand around him, he transfigured his robe into a suit. A suit he usually wear during his days going around visiting muggleborn, his fond smile slowly turn into a frown as he remember why he stop wearing this suit and going full robe afterward.
Letting out a small sigh, Dumbledore look at his wand in his left hand and flick his right gripping another wand and inspected it to. He move his shoulder a bit feeling the suit was a bit loose but considering what he was gonna do and his now old physique those loose space is needed.
'Expecto patronum'
Dumbledore flick both wands to the side. His left shoot out the Phoenix, his right the spell took form of a quadrupedalism being. It's hight from its head reached Dumbledore chest, it's four legs are langky but pecks with explosive muscle. Even if it's being an translucent wisp of silver energy, it's power rediating can force all that is dark away.
Dumbledore look to his right and chuckle abit for he can feel that his patronus is mad at him. That something he cannot fix right now but only time and regularly summon this Great Dane, his original patronus out. The silver Phoenix to came down landing on its back and singing a silent tune with Dumbledore belief only a patronus can hear or someone with a heart of....
A flash of fire of red and gold pulled him out of his musing and he realize he had reach the trashhold to enter the safe zone. Pushing all distracting thought to the back of his mind, Dumbledore look up and saw his friend Fawkes flying in circle above him. Swiftly,the majestic bird flew down landing on Dumbledore shoulder and moving its head atop of Dumbledore now open maw. Fawkes drop a dozen drop of tears, finish doing so Fawkes flew up again and cry signaling that he is prepared.
Dumbledore took a deep breath, feeling the energy roiling within him. Now, all the ingredients are ready but one and the intended location is reached. Thinking that the time is right, Dumbledore ready himself to complete the ritual that he is maintaining since a month ago. A ritual so dark so vile one do not do it in a ritual circle nor on another being or required one for a sacrifice only magical energy one must collect within the month period. What make it vile in the eyes of the masses that wielded magic, one must do this ritual on one own body effecting the very root of one's being. What's more, if one decided to sire a heir the corrupted root will be inherited until the line dies off.
With a step entering the zone, multiple presence make its self known as they rush towards Dumbledore. The silver Phoenix and The Great Dane move instantly as pure white energy shine from them push the dementor away as Dumbledore run deeper into the zone. Dumbledore move towards a singular dementor that his patronus manage to separate from the flock, stabbing the wand on his left into its chest the wand on his right into its temple. The dementor shreek in pain as suction vortax cover the wand pulling it's energy into Dumbledore.
He grits his teeths so hard that it felt like it's breaking, his muscle pulse unnaturally, bones cracking and somehow it feels like it's molding within his body like how it felt when he first time drank that particular potion. Suddenly, the dementor grip the side of his head and pull itself towards him. As if it's sensing what was happening, the others started to rapidly flow to his position. The Phoenix and Great Dane shine brighter as the pure magic pulse, the patronus did their best to push the dementor away but it was to many and they were bypass. The dementors got near and Dumbledore sense them but couldn't do anything as he try to push the one in his grasp away from himself as he consum it's essence and magic.
A wall of fire encircle Dumbledore and Fawkes cry above him. The fire burn with rage and disappointment not towards those outside the wall but at his old friend,his companion for what he was doing. The only reason he help and not abandon his human companion when he was told what the ritual is and to what extent the tabo that will be committed, is that Dumbledore said that everything will be reversed in a way that only one person can do. Fawkes know who this person is, no one magical being that had exist that doesn't know this person. If his companion wish to meet this person than this act agenst magic itself is acceptable for any less will be an outrage and disrespect. What mors, this person was his sub-parents after his own abandon him after his first burn day. That is what he drain nearly half of his resurve to assist his companion just to meet him again but even with this motivation the revulsion is still there just suppress slightly. Dumbledore felt the fire sting his face but not burning, looking up at the bird he just chuckle. The dementor lounge again but he push it back as he continues to siphoning it to himself.
The entanglement continue as the patronus and Fawkes kept the dementor at bay until Dumbledore shouted in terror and pain. The dementor that he had captive is nothing but a husk as it fell turning into dust, the other dementors shreek and shout as they flow away in defeat unable to save one of their own. The two patronus and Fawkes got near but still away from Dumbledore, looking at him twitching and convulsing in pain as his eyes fill with terror.
Dumbledore fell to his knees as he shout and twitch in pain and horror at what he saw as his body and magic assimilated with all the magical energy that he had consume and held within himself. As the mixture fuse with his core, Dumbledore saw everything that connected with them.
The vibrent life force from The Elixir of life colidid with The Hollow Grasp of the Dementor magic collided with each other it's nature push it apart but the ritual forcing it together. The Phoenix Tears acted as a cauldron the holds the two opposites from overflowing throughout Dumbledore being, due to the volatile nature cause by mixing the two opposites Fawkes had fed Dumbledore an overdose amount of his tears. The Dementor essence act as the fuel and binding the opposite together but as any potion Master and arithmancer knows, side effects is unavoidable. As the Dementor essence burn, it's afterburn leaks out into Dumbledore, unlike the opposite that is contain by the Phoenix Tears.
Dumbledore saw everything, the soul's and it's memory that the Dementor suck out of its victim along side that siphon memory of those that had inhabit within Askaban.
Dumbledore saw how this Dementor came to be, how it's was force to do before what remain of itself was gone. Later, it's act as the Warden to Askeban when The Ministry reach the shore of this island and everything that it had done until it's end by Dumbledore.
