Flashback

The battle of Hogwarts was won by the side of light over sixteenth months ago. Severus Snape manage to survive in the Shrieking Shack long enough for Hermione to assist him and portkey him to 's in somewhat stable condition thanks to bezoar she had in her bottomless purse. But tonight was Ministry's Gala, the entire order of the Phoenix that survived was there including Severus Snape who was released earlier this month. The evening has finally progressed to dancing and Hermione had finally worked up the nerve to ask her old professor for a dance.

However, something that was brewing since sixteen months chose this moment to let their presence be known to Wizarding Britain.

What the first Army that was hidden in the cave isolated from the world, the second army was in an open space assessable to anyone or anything after Tom Riddle's protections faded with his passing.

When the protection fails the lake became the most favorite spot for illegal waste dumping for Muggles. It first started when one CEO decided to illegal dump some toxic oil and gas byproducts in the lake the Inferi were Inferi attack when disturbed by outside contact.

So waste from big pharma, nuclear, healthcare, manufacturing industries made their way into the lake and interacted with each other and the Inferi.

Severus was shocked that Hermione approached him but he graciously accepted her offer and started to twirl her around the dance floor to an Argentine Tango. As Severus' lips were nearing her hand, all hell broke lose.
