One possibility could be that in the fanfiction, Jon Snow discovers the Valyrian steel in an ancient castle's armory. Maybe it was hidden away for centuries, and his discovery sets off a chain of events that changes the course of his journey.
Valyrian Steel could be part of an ancient prophecy in the Harry Potter fanfiction. Maybe it's said that only a wizard with a pure heart and a connection to the founders can wield a weapon made of Valyrian Steel. Harry, being the hero, is destined to find and use it to defeat the ultimate evil. It could also be that the Valyrian Steel is hidden in a different magical realm that Harry has to travel to, which would introduce new and exciting settings into the fanfiction.
He could use it to defeat a powerful enemy. Valyrian steel is very effective against certain threats in the 'Game of Thrones' universe. So, when Jon Snow finds it in the fanfiction, he might be able to slay a great foe that was previously unbeatable.
One idea could be that Harry discovers a hidden Valyrian Steel sword in Hogwarts. It might have some ancient magic tied to it that could help him in his fight against Voldemort. Maybe it has the power to cut through dark magic spells easily.
There were some differences in appearance and texture between the ice jade and the ice jade. The ice jade looked like ice shards. The foundation was uneven, and the grains and cotton could be seen with the naked eye. It was less transparent, but it had a higher water head and clarity, so its value was higher. The glutinous ice jade was more rigid and transparent. Its internal structure was hazy and mostly translucent. The moisture of the Icy Glutinous Seed was slightly more turbid than the Icy Glutinous Seed. Therefore, no matter which one was better, it still had to be analyzed in terms of water, color, craftsmanship, size, and many other aspects.
