"They aren't human, per se, they are entities that have taken forms not their own. The reasoning behind this is the fact if they were to reveal their true forms, whoever unlucky enough to see them would be incinerated." Dumbledore began. Foaly made a dismissive 'piff' noise.
"That is impossible." Foaly said.
"They exist outside possibility." Dumbledore said. That made Foaly stop talking. Trouble looked confused.
"How can anyone live outside possibility?"
"They were the ones to create possibility. They created it yet they are not of it," Dumbledore answered, leaving his audience quite perplexed. "They are called the Ancients, they have existed as equals and as sisters to each other. They are older than time itself, and a thousand times more powerful than everyone that has lived in time. However, they were not alone in power."
"The enemy of old…" Harry whispered.
"Correct. This entity was the very heart of all things evil. The Ancients realize there must be balance between good and evil, but the entity strived for corruption and despair. It had come to a point he had destroyed everything and the very reality of all the worlds threatened to give out and to become nothing. Furious at what it did, the Ancients imprisoned the entity within his own power, making what was once an ability to become confinement. However, the Ancients couldn't do this easily. The entity was the only one to be able to appose them. It nearly matched them in power, and that is why they are so worried about this situation with it."
"If they can't handle it, than how do they expect us to?" Doodah asked indignantly.
"I'm getting to that. They are able to change their form at will, and a few decades before the time of the fairy Battle of Taillte each one of them fell in love with a different mortal. Obviously, they couldn't tell the mortals who or what they were, so they took the forms of mortal females. Each one of them bore only one child, and to this day each one of them only has one descendant. When their husbands died, however, they decided to take the forms of young human children to forever symbolize the fact they would never let themselves love like that again. Their descendants inherited their power, but due to their mortal blood they could only unlock the full potential of that power in a time of great need and so far, no descendants have been in such a time."
"So they expect their descendants to handle it even though they can't? I'm sorry, but I cannot find an advantage a human would have over something like that entity. If anything, I would think that a human would have a disadvantage since they are able to die!" Minerva said. Dumbledore nodded.
"Logically, yes you are correct. But like I said, they exist outside of logic. The one thing their descendants would have that would give them leverage over the entity was the fact it can't steal their power," Dumbledore received many blank looks. "What I mean is, since this entity is so similar to the Ancients, it are able to absorb their power through a specific spell. However, it can't do the same to their descendants. Their descendants have so much mortal blood running through their veins, the entity is too dissimilar to absorb their power. It is basically up to us to make sure their descendants don't die." Dumbledore finally finished. Trouble rolled his eyes to the ceiling.
"I'm not sure I can take anymore surprises today!"
A/N
Ah poor Trouble. Your surprises aren't over yet! I think another three or four can do the trick! I'm SO SO SO sorry about the length, but I thought that the explanation for the Ancients deserved a chapter for its own. I don't own anything, and I want you to review. You know the drill.
