The blue moon twinkled in Dumbledore's pale blue eyes as Harry stared in to them. He had used the Resurrection Stone to see the old headmaster once again; he had missed Dumbledore's kind advice and wise guidance.

"That was extremely brave of you to go and fight Lord Voldemort." The headmaster's eyes twinkled as an eye-creasing grin spread across his gentle face. "His Reign of terror has ended, but the darkness will still seek another way to protrude the light," Dumbledore hinted as he looked directly at Harry.

"So...are you saying there will be other wizards who will try to bring threat to the wizarding world?" Harry asked, his brow furrowing as he considered the possibility. He had risked his life to save thousands of wizards, but were there still others out there? Some lurking in the darkness, just as powerful as Tom Riddle? The thought sent a chill down his spine, causing a subtle shiver to course through his body.

Dumbledore nodded gravely. "Not only the wizarding world, but the world of Muggles as well," Dumbledore replied, stroking his long white beard thoughtfully. "Harry, other groups of notorious wizards exist as well. They have been hiding from the world this whole time, afraid they would be hunted down by Voldemort if they were in the way of his path to domination. Now that he has fallen they are free to do their own plans."

"But I'll be there to stop them," Harry said with a smile on his face. He had stopped Voldemort - of course he could stop the other, weaker, power-hungry wizards.

Dumbledore frowned and said, "True, but that doesn't mean you'll succeed."

Harry's mouth turned down in a frown as well, and it seemed as if all the confidence he gained from that statement was just blown away, like a dust speck on the wind. "What do you mean, Professor?" Harry inquired, scared, but excited and curious, too.

A humorless chuckle slipped through Dumbledore's lips. "You were extremely lucky. Voldemort was too full of himself and he did not take precaution in anything. That's why he had so many weaknesses against you Harry," replied the old headmaster. "You see, Grindlewald's army didn't really die with him. They are still alive and to this day they are planning the rule of the wizarding world. Since the Dark Lord has fallen they'll make their move immediately. News gets around quickly; they'll want to act as quickly as possible. They might attack again in a few days, months, and maybe even years...but the evil in this world will not just cease to exist now that Voldemort is gone. Harry, what I'm trying to say is that you must be prepared for anything! You must be ready to strike at any given moment, and be careful if they decide to attack later. Your children - maybe even your grandchildren - are in serious peril."

So many thoughts were swirling around Harry's head, making him dizzy. But he tried to regain the calm, passive look he had worn before. "I will be ready, Professor," he assured him firmly, "and when they strike I'll be there." Suddenly, he beamed childishly, like he was back in his first year at Hogwarts, looking for adventure. Uttering a handy spell, the tip of his wand lit up.

A small smile touched the old headmaster's lips. "Good," Dumbledore said, and his soul zoomed right back in to the Resurrection Stone as Harry flipped it over in the palm of his hand. He turned around, and headed back to the half destroyed Hogwarts, soon to be hero once again.
