Author's Note 2: Hogwarts has a number of Formal Clubs. Chess and Gobstones are both acknowledged clubs. Choir and Instrumental music clubs. The Curse Breaker's Club which is open to 5th years and above. It deals with minor cursed objects sent to it by various magical people.
After the meeting Hermione went to her Ancient Runes study group and Ron after he put his notes away went to the his chess club leaving Harry to fend for himself for entertainment . Since the weather was miserable he decided to head to one of the secret rooms he found. The one he had in mind had trunks full of interesting things. Since he didn't want to stop for lunch half way through exploration he headed to the kitchen to pick up some sandwiches and a thermos of tea. An elf named Finny made him sandwiches, packed a couple of bake-well tarts and an ever filled thermos of tea.
The room he wanted to explore was just off the Grey Lady's Garden at the foot of Ravenclaw tower. He crossed the empty garden glad that some enterprising wizard had covered the garden over with a glass roof so it was dry. From what Hermione had said this was the place Rowena Ravenclaw grew her most delicate plants. Now it housed some dwarf citrus trees. He slipped behind the statue of some former Ravenclaw head of house though no name was ever given for the statue. The lock is similar to a puzzle box that you have to move the stones in the mosaic in a certain pattern. It had taken him several days to figure it out.
The when the door opened he slipped in and closed it behind him. A whispered word had the lamps in the room light up giving him plenty of light to see by. The room was as he left it. He set his lunch on the table then headed to the first trunk. He took a deep breathe concentrated on his mage sight. No magic on the chest good he opened it. Dozens of small identical boxes fit neatly inside . He took one out and opened it at random. A dozen crystal bottles. He lifted one out to see if it was labeled. It was. Asp of Fire was what the label said. It contained what looked like ash. Another in the same box was labeled Blood of Unicorn willing given. It shown a lovely silver.
He'll have to bring Snape here to check out the box. It just may be old potion's ingredients, the labels said different. The next trunk was what he thought to be witches clothing. The clothing all had the faint light of preservation charms on them. At least he thought they where a witch's he couldn't imagine a wizard wearing them. He closed that trunk. The third chest was books that had no magic on them. He opened one at random.
On this day the year of our Lord 1251 on Candlemas I put pen to parchment to record the words of our Seer, Brother Thomas of Bethwyck.
The book recorded the prophecy in what Harry had come to accept as 13th century English yet the words before and after the prophecy where in formal clearly understandable if a bit archaic Modern English. There was a footnote at the end of the prophecy that stated simply Fulfilled. He flipped through the pages to find a boil cure recipe different from the one taught in potions. The observations on a faint comet in the night sky to the east just before Sunrise. A recipe for mead and three for beer. Several orders for Wool cloth from Scarbough Faire. A second Prophecy by the Seer, Brother Thomas. The breeding of a pair of Gryphons and the number of eggs in the clutch.
Harry placed that book aside and took out another one. Different handwriting and it is mostly in Latin. He set it aside his Latin is up to translating it. A third book is one of simply accounting. It lists tithes paid to Hogwarts from 1362 to 1365.

Harry flips through the pages. The entries make interesting reading but not what he wanted to find. He put the books back and closed the trunk mentally labeling that trunk accounts and diaries. Several other trunks reveal more clothing both mens and womens. The trunk of books that was next contained dates from about 1589 to 1643. The account books are very similar to the ones from the first trunk. After careful exploration he comes to the conclusion that there are roughly 5 trunks of clothing to 1 trunk of books. With Harry finding 2 more trunks of potions ingredients.
When the bell for tea rings at 4 Harry closed everything, collected his thermos and the food wrappings and headed to the great hall for tea. He set the thermos on and empty food wrappings on the small table just inside the door. He notes he wasn't the only one who collected food from the elves that day. Snape was alone at the head table so Harry went up to him.
"Professor Snape," he called politely.
"Mr. Potter?" Snape queried.
"I found a room off the Grey Lady's Garden. It's behind the statue of the nameless Ravenclaw head of house. It's loaded with trunks. Most are clothing from centuries ago but three contain what I think are weird potion's ingredients. I read the labels on two of the bottles. One was labeled Asp of Fire and the other was Unicorn Blod Freely given. After that I didn't do anything with those trunks." Harry told him.
"There are three potions that use Unicorn blood that is freely given. All three are last ditch healing potions. What was in the bottle?" Snape asked intrigued.
"Silverly liquid. I couldn't tell if it was Unicorn Blood or not. The Asp of Fire contained what looked like ashes similar to what the ashwinder left over Christmas." Harry replied. "There was also books from about the 13th century to the late 18th. A couple had potions recipes in them though most where account books." Harry explained.
"Did you manage to get your homework done?" Snape asked.
"I don't have anything due this week. It's mostly practicals and reading." Harry replied.
"How do you know that?" Snape asked.
"Ron and his patterns." Harry grinned.
"Go have your Tea." Snape dismissed him.
At that time Prof. McGonagall arrived. "Good Mr. Potter. We will be checking the wards at First light please bring your broom with you. Unlike Slytherin and Hufflepuff the Gryffindor wards are out side." McGonangall ordered.
"Yes, Prof. McGonagall." Harry acknowledged her. Then he headed to the Gryffindor table for some tea and yes, scones with Devonshire cream and jam.
