Sirius's son

Slytherin's locket

When the two arrived (Having rely on Eliza's twin bond with Harry) they entered the tent to see Ron propped up on a bed. Turns out Harry had retrieved Mad eye's electric blue eye from Umbridge (the bitch actually kept it) and gave it a proper burial. Then Harry showed them the Horcrux.

"Oddly beautiful," Rigel said holding the Horcrux. "Well, it's a shame to destroy it."

"Yes. Good plan. ....but how?" Harry asked.

Rigel grinned activating the sword of Slytherin. "You know what's so special about this sword guys?"

They shook their heads.

"The swords' properties is that it can observe any poison ."

Hermione gasped. "The sword's imbibed with basilisk venom."

Rigel nodded. "And we can destroy it right here and right now."

When Ron woke up, the four told everything, and although he was a little bit pissed that he wasn't awake during their conversation, he didn't mind.

"How are you going to open it?" asked Ron. He looked terrified

 "I'm going to ask it to open, using Parseltongue," said Rigel clutching the sword tightly. 

Everyone gulped looking at Rigel 

"On three," said Rigel, looking back down at the locket and narrowing hiseyes, concentrating on the letter S, imagining a serpent, while the contents of thelocket rattled like a trapped cockroach.

"One . . . two . . . three . . .open." 

The last word came as a hiss and a snarl and the golden doors of thelocket swung wide open with a little click.Behind both of the glass windows within blinked a living eye, dark and handsomeas Tom Riddle's eyes had been before he turned them scarlet and slit pupil 

Rigel raised his sword and brought it down towards the locket. 

There was a bright light and Harry and Eliza writhed down on the floor letting out a loud scream. 

But then it was over and it was Rigel holding the pieces that were once Salazar Slytherin's locket.

"Reparo." He hissed and the locket repaired itself as if it had never been destroyed

"What?" He asked as everyone looked at him in disbelief. "You seriously think I'll just dump my ancestors' locket?."

Eliza shook her head but she understood her boyfriend's obsession with preserving magical artifacts. 

"Well that's one down," Ron said oddly cheerful. "Now what?"

The problem was that there were other Horcruxes out there, but neither of them had the faintest idea where they could be. Somehow you-know-who (They stuck with you-know-who as Rigel's father once mentioned that the name was a taboo in the last war) didn't even know that one of his Horcruxes was destroyed.  

tempers were also running high. With no food. Hermione had not packed any food in her magical bag, as she had assumed that they would be returning toGrimmauld Place that night, so they had had nothing to eat except some wild mushrooms that Hermione had collected from amongst the nearest trees and stewed in a Billycan. After a couple of mouthfuls, Ron had pushed his portion away, looking queasy; Harry had only persevered to not hurt Hermione'sfeelings. Rigel just drank water.

Then the next night, Harry and Eliza had a dream about Gregorovitch

"He found Gregorovitch. He had him tied up, he was torturing him." Eliza had said
