The large building was standing over the cloudy sky. The sea battered one side. The fire escapes decorated the opposite one. The building was made up of old, greying bricks and it had been a decade since the last time they had been cleaned. Dorcas Meadows stood in the hidden room of the building. Dumbledore had covered the only entrance with a password protected portrait. She carefully marked the date in her journal. She began to write down what she knew about what she would have to study. Next she wrote down some of the theories she had been working on. She heard the portrait hole swing open. She did not look up. She was expecting that specific visitor. Marlene McKinnon kicked the chair in front of her.

"Watch it, Marls" Dorcas said

"Sorry, I can't see a bloody thing over this box" Marlene said. She was carrying a large chest

"You got it from Dumbledore?"

"Yeah, why?" Marlene asked

"Good, I've been waiting for it" Dorcas said

"What is it?" Dorcas pushed open the chest. Inside were 6 perfectly perfectly preserved dragon eggs.

"Dragon eggs. Their shells are almost indestructible. If we can figure out how to destroy one, we figured out how to destroy a Horcrux"

"Are there Dragons in there?" Marlene asked

"No. They're like the chicken eggs you get in a supermarket" Dorcas said "Right, I wrote down a couple of suggestions for spells and poisons we can try." Marlene took out her wand and flicked it. A fireball flew at the eggs. It bounced off and Dorcas had to duck in order to avoid being hit. The fireball caused the chair behind her to be set ablaze. She put it out with a stream of water. Dorcas pinched the bridge of her nose

"It was worth a shot" Marlene said

"Marlene, those are dragon eggs. They are designed to respell fire!" Dorcas shrieked

"Well we weren't gonna know until we tried." Marlene said

"Ok, from now on, I will lead our experiments," Dorcas said. Marlene grumbled. She took a pair of goggles and gloves for herself and then threw another pair at Marlene. Dorcas walked over to her distillation station. She took the vile that had been reduced to a thick purple paste.

"What is that?" Marlene asked

"A combination of Acromantula venom, Belladonna and Hemlock extract and wych elm bark. It was apparently concocted by Morgana Le Fay to kill Merlin. I can't verify that though" She used a spatula to take out the extract and placed it on the eggshell. It smoldered for a couple of seconds before staying still

"Do you think-"

"Only one way to find out," Dorcas said. She scraped off the extract to reveal a perfectly intact eggshell. "I guess not" She placed a cap on the bottle and removed her goggles.

"Do you have any other ideas?" Marlene asked

"So far, just this, Gu and Fiendfire. I had really hopes for this one"

"What about some animal venoms?" Marlene sake d

"What do you mean?" Dorcas asked

"Well, that's a lot of spells and potions. Why not try some straight animal venom. I'm sure Fantastic Beasts will have some suggestions."

"Worth a shot"
