Once breakfast was over, they went to the lounge, where Sirius called for Kreatur. Under Hermione's indications, he ordered the elf to tell them what had happened with the Medallion.
"Did master Regulus returned to the cave?" Edmund asked.
"Master Regulus never returned anywhere. The Dark Lord killed him a day after he returned."
"Can you take us to that cave, Kreatur?" Hermione finally asked.
"Kreatur doesn't want to go back." the elf croaked. "This place is bad, nasty, nasty."
"I know, Kreatur. But to avenge Master Regulus, we have to go there, and get something back."
"The medallion the dark lord hid there is cursed. Bad, nasty!"
"And this is why we have to destroy it. Please, Kreatur, take us to the cave...!" Hermione pleaded.
"You're not going anywhere." Edmund intervened. "You stay here, you rest. I'll go."
"What ?! Don't be ridiculous, Ed, you need a wizard with you."
"This house is full of wizards." Sirius interfered. "Your friend is right, you need some good rest. You're exhausted. Any of us can go with him."
"But..."
"I'll go." Charlie decided. "As the oldest one of Weasley sons, here, I have more experience."
"But, I..." Hermione tried.
"Hermione, I'm warning you." Edmund threatened. "If you keep insisting, I'll ask Fred and George to knock you out."
And so the young woman conceded.
"You will have to cross a lake." she explained. "Don't touch the water, there are inferrii in there. There's an island in the middle of the lake with... something to drink. The Medallion is at the bottom of the recipient."
"Understood." Edmund said. "Kreatur, get us there, please."
The elf reluctantly took both young men hands, and they apparated.
