Unforgivable Truth was the name given to an event of the Calamity.[1]
Adversaries Event: Dragons and Beasts[]
Part I (31 May–7 June 2021)[]

Harry and Hermione work together to create a surge based around the events of their first year at Hogwarts. Will their experiment to use the Calamity to restore Ron's memories prove sucessful?[1]
Brilliant Hogwarts Corridor[]
- "I've just heard from Constance. Considering the sorts of Foundables she and the rest of the SOS Task Force are seeing, I'd say our first experiment was a success. We were able to combine our memories of our first year at Hogwarts to create one unified surge."
- — Hermione Granger[src]
- "You really think creating surges based on our adventures with Ron will restore his missing memories?"
- — Harry Potter[src]
- "Yes, and I'm confident our second experiment will prove it. You saw it yourself during the last surge, Harry. Every time we returned a Foundable, Ron was suddenly able to recall a related memory. That can't be a coincidence. The Calamity must be the key to restoring Ron's memories."
- — Hermione Granger[src]
- "Well, we've exhausted all our other options, so I sincerely hope you're right..."
- — Harry Potter[src]
- "Don't worry, Harry. If everything goes as predicted, more than one question will be answered by this surge's end."
- — Hermione Granger[src]

Brilliant Mountain troll Return To: Girls' Toilets, Hogwarts Castle |
Despite their diminuitive intelligence, mountain trolls are exceedingly dangerous. Given this, it is astonishing that Harry Potter and Ron Weasley managed to dispatch one at Hogwarts as mere first-years. Quirinus Quirrell set said troll loose as a distraction during an attempt to steal the Philosopher's Stone. |

Brilliant Dragon egg Return To: Hagrid's Hut, Hogwarts Castle |
As a Class A Non-Tradeable Material, dragon eggs are not to be traded or owned. However, unscrupulous witches and wizards have been known to peddle them to naive dragon enthusiasts. One such victim was Rubeus Hagrid, who won a Norwegian Ridgeback egg off a stranger in a game of cards. This stranger turned out to be none other than Professor Quirrell in disguise, who used Hagrid's love of dragons to get information on Fluffy. Should you find yourself in possession of a dragon egg, it is advised you return it to the nearest Dragon Sanctuary or Ministry representative. |

Chocolate Frog Return To: Honeydukes Express, Hogwarts Express |
A favourite treat amongst witches and wizards of all ages, Chocolate Frogs are charmed to hop like a real frog once opened. Each one comes packaged with a Famous Witches and Wizards Card, which features a portrait and brief biography of a notable witch or wizard like Morgan le Fay, Merlin, and Albus Dumbledore. Many a Galleon has been spent in pursuit of a complete collection. |

Brilliant Quarreling Professors Snape & Quirrell Return To: Hogwarts Castle |
Severus Snape and Quirinus Quirrell never quite saw eye to eye during their shared time as professors at Hogwarts. According to student testimony, the two were prone to bickering. Initially it was assumed that Snape, jealous of Quirrell's position as the Defence Against the Dark Arts Professor, was bullying the timid man. After Quirrell's ties to Voldemort came to light, however, it was believed that Snape had seen through Quirrell's deception from the start. |

Harry's Troll Bogeys-Covered Wand Return To: Harry Potter |
Eleven inches long, made of holly wood, with a phoenix feather core, Harry Potter's wand is as unique and powerful as its wielder. The phoenix who provided its tail feather for the wand only did so for one other - Voldemort's. Garrick Ollivander predicted this wand would be used for great things, though it's doubtful that included being shoved in a troll's nasal cavity. |

- "You were right, Hermione! Bits and pieces of Ron's memories really do come back to him when we return related Foundables. I'm not sure how that's possible, but I'm not complaining."
- — Harry Potter[src]
- "My theory is that the Calamity is functioning like a Pensieve. Rather than Obliviating Ron, Kit Gerrard, and Flavius Flint's memories, I believe The Unforgivable used the Calamity to snatch and lock them away. Surges provide a channel for some of the trapped memories to "escape"."
- — Hermione Granger[src]
- "So as long as we continue to use our shared memories to manipulate the Calamity, we should be able to return all of Ron's memories?"
- — Harry Potter[src]
- "Theoretically, yes. Though it will take time before he's completely back to himself. I wish we could simply force The Unforgivable to release them, but, well... I haven't even been able to uncover the identity of their mole yet.
I haven't exhausted my list of possible suspects yet, so I still have hope this will work. But we may want to start considering our next course of action should it not." - — Hermione Granger[src]
Adversaries Event: Feared Wizards[]
Adversaries Event: Ancient Norwegian Ridgeback[]
Second Anniversary Celebration[]
Part II (21–28 June 2021)[]

Hermione's secret mission to uncover the identity of The Unforgivable's mole continues. Will she root out the corruption? Or will The Unforgivable be one step ahead again?[1]
Brilliant Trapdoor Chamber[]
- "I don't know why I didn't think of creating a surge together sooner. With our combined efforts, it was much easier to fend off The Unforgivable's attempt to steal control of the surge between waves."
- — Hermione Granger[src]
- "The Unforgivable must have realised that we know how to use the Calamity to restore Ron's memories. Should we be worried about that?"
- — Harry Potter[src]
- "Perhaps, though I'm more concerned that they've realised I'm using Veritaserum to attempt to expose their informant. I've heard plenty of confessions - including a few that I wish I hadn't - but no one's implicated themself so far."
- — Hermione Granger[src]
- "Perhaps there is no mole in the Ministry after all? We have plenty of circumstantial evidence, yes, but no definitive proof..."
- — Harry Potter[src]
- "No, someone close to us has definitely been leaking our plans to The Unforgivable. The only question is - have I yet to 'interview' the culprit? Or have they managed to resist the Veritaserum's effects? Well, I suppose we'll find out which is true soon enough, won't we?"
- — Hermione Granger[src]

Brilliant Philosopher's Stone Return To: Underground Chambers, Hogwarts Castle |
For centuries alchemists have attempted to create the legendary Philosopher's Stone. To date, however, the only known maker is renowned French alchemist Nicolas Flamel. Capable of transforming any metal into gold and of producing the immortality-granting Elixir of Life, Voldemort once attempted to steal the Stone. Thankfully, he was foiled by Harry Potter and his friends. |

Brilliant Three-headed dog Return To: Third-floor corridor, Hogwarts Castle |
Very few witches or wizards have encountered a Three-Headed Dog in the wild. Even fewer have encountered one in the third-floor corridor of Hogwarts Castle. Those that have can attest that three heads are, in fact, deadlier than one. Because of that ferocity, Fluffy, Hagrid's pet Three-Headed Dog, was even entrusted with guarding the Philosopher's Stone. |

Broken Winged Key Return To: Underground Chambers, Hogwarts Castle |
This winged key was expertly charmed by Professor Filius Flitwick as a part of a puzzle designed to protect the Philosopher's Stone. Its bright blue wings were broken by Quirrell during his attempt to steal the Stone. Ironically, this enabled Harry and his friends to more easily pursue the scheming wizard. |

Underground Chamber Strap Door Return To: Third-floor corridor, Hogwarts Castle |
Guarded by Fluffy, Hagrid's pet Three-Headed Dog, this trapdoor led to the Underground Chamber that housed the Philosopher's Stone. First, however, one would have to navigate past seven obstacles, each more treacherous and tricky than the last. |
|
![]() |
Wizard's Chess Knight Return To: Underground Chambers, Hogwarts Castle |
The fourth obstacle protecting the Philosopher's Stone was a life-sized game of wizards chess. In order to proceed through the underground chamber, one had to take the place of one of the chess pieces and win the game. Harry Potter assumed the role of a bishop, Hermione Granger played as a castle, and Ron Weasley functioned as both a knight and the game's commander. In the end, Ron valiantly sacrificed himself to the white queen so Harry could checkmate the king. |

- "Miss Granger, what a surprise. Can whatever you've come to discuss wait? I'm rather busy..."
- — Gareth Greengrass[src]
- "No, I'm afraid it can't. In fact, I'd say this talk is long overdue. Gareth, you're the mole who's been leaking our plans to The Unforgivable, aren't you?"
- — Hermione Granger[src]
- "Don't be ridiculous, I'm no mole. I'm one of The Unforgivable's most respected members.
What am I saying...? You...! You put Truth Potion in my tea, didn't you? But how? I never took my eyes off my cup!" - — Gareth Greengrass[src]
- "I assumed a guarded wizard like you wouldn't. That's why I put it in your milk instead. Now it's my turn to get some answers..."
