Witch Valley
Ireland MacGillycuddy's Reeks, located in County Kerry, Republic of Ireland, stretches for 19 kilometers and is adjacent to the Lakes of Killarney in Killarney National Park. Of course, in the wizarding world, this area is also under the jurisdiction of the Great Britain Ministry of Magic, rather than an independent state.
The boundaries and sovereignty of wizarding nations largely overlap with those of the Muggle world, but examples like Ireland are not unique or isolated.
For example, North and South Korea in the Muggle world are actually under the same regime in the Wizarding World, namely the Korea Ministry of Magic; another example is that Transylvania in the Wizarding World is not part of Romania as it is in the Muggle world, but is under the Transylvanian Ministry of Magic, which has an independent regime.
The MacGillycuddy's Reeks stretches over 19 kilometers and includes Carrauntoohil, the highest peak in Ireland. On sunny, pleasant days, many Muggle travelers come here to hike and enjoy the scenery.
Of course, due to the Muggle-Repelling Charm, Muggle will subconsciously overlook many strange details of the mountain path, such as the presence of empty wastelands that shouldn't be there at certain points in the journey.
After the implementation of International Statute of Secrecy, many wizards chose to settle here, especially in the area near Carrauntoohil, where there are at least two villages where wizards gather.
Wizards who are close to Muggle often choose to live in the Coomloughra Valley, a village similar to Ottery St. Catchpole where wizards and Muggle live together, located in the western part of Carrauntoohil.
Separated from this village by Carrauntoohil is the Coomloughra Valley, located to the east of Carrauntoohil. Known as "Hag's Witch Valley," it is the home of extreme Pure-blood wizard who reject Muggle and refuse to associate with Muggle.
(Note: Because Witch Valley is easier to remember, for the convenience of the reader, this article will use "Witch Valley" instead of "Coomloughra Valley" from this paragraph onwards.)
Because the Gaunt family inherited their ancestor Slytherin's extreme reverence for Pure-blood beliefs, they all chose to settle in Witch Valley and establish their family there. This situation only changed with the generation of Isolt Thayer's mother, the Founders Ilvermorny. Isolt's mother, Leona Gaunt, fell in love with William Thayer of the Sayre Family, a prominent Ireland wizarding family from the neighboring village, and married him. After their marriage, they moved to Coomloughra Valley and learned how to get along and live with Muggle.
This angered Leona's sister, the infamous dark witch Gormlaith Gaunt. One night, Gormlaith sneaked into their house and burned them all to death with Fiendfyre Curse, leaving only Isolt alive. Gormley took Isolde back to Witch Valley to "train" her, teaching her Dark Arts and forcing her to watch curses being used to torture Muggle. However, Isolt was not successfully brainwashed. After learning some magic, she stole her aunt's wand and smuggled herself to the New World of North America. After a series of exciting adventures, she founded the Ilvermorny Academy of Magic.
This is also why Skylar chose to let Dobby Apparition to Witch Valley. Given Slytherin's strong preference for Pure-blood Supremacy, if they were to leave a legacy, it would certainly be near this village that rejects Muggle, not the village on the other side of the mountain.
The two, along with a House Elf, slowly explored the surrounding area according to the map's directions. Finally, after passing through an extremely hidden mountain path and a dark, sunless cave, they arrived at a spacious basin surrounded by mountains.
Skylar was certain this was the location marked on the map, but there was nothing unusual about it. Sarf and Dobby wandered around, searching for any hidden mechanisms.
Having gained experience from exploring Hufflepuff's Caverns, Skylar immediately used his Magic Eye to scan the surroundings, where a faint magical fluctuation permeated the air.
He followed the fluctuations of magical energy step by step, and finally discovered a different kind of magical energy fluctuation on a rock. He pushed the rock aside and found a magical mark carved on its surface: two ferocious green pythons with bared fangs, intertwined around something resembling a scepter. Skylar finally realized that he had found the right place.
He beckoned Sarf and Dobby over.
"Is this the Gaunt family crest?" Sarf frowned slightly. "Why does it look different from what I know?"
"No, this isn't the Gaunt family swastika," Skylar explained, "But rather the original swastika of the Slytherin family. Because the Slytherin name carries powerful magic, its direct descendants couldn't bear the name and had to change their surname to Gaunt, resulting in subtle changes to the design of the swastika."
"So, what do we do now?" Sarf tried to command the two giant pythons on the mark in Parseltongue, but received no response.
Skylar pondered for a moment, then said, "What Slytherin values most is nothing more than the bloodline of wizards. And his most powerful magic is Dark Arts and Legilimency. From these two points..."
Skylar took out his wand, lightly drew it across his palm, and bright red blood flowed rapidly, dripping onto the magical mark. Then he pointed the wand at the mark and loudly chanted, "Legilimency!"
A green light flashed across the magical mark, Skylar's blood was instantly absorbed by the two green pythons. The two green pythons seemed to come alive, emitting loud hissing sounds, and slowly loosened their coils from the scepter. The scepter, now unsealed, transformed into a stream of light and shot into Skylar's head.
This is a method similar to the Pensieve, which allows one to leave their memories in the present world through magic. These memories can only be activated through specific means, allowing them to be directly sent into the consciousness of the successor.
