The Legend of Zelda: Tears of the Kingdom (TotK) is set in the same world as Breath of the Wild. Link awakens on a sky island. The story involves Zelda disappearing and Link's quest to find her. Ganondorf is the main villain again. Link has to explore the sky islands, use his new abilities like Ultrahand to solve puzzles and build things. He also has to traverse the surface world and the depths. There are various races and characters that help Link on his journey, like the Sages. Overall, it's a story of Link's heroism and his journey to save Zelda and Hyrule from Ganondorf's evil plans.
One key element is Link's journey. He has to traverse different terrains like the sky islands, the surface, and the depths. Another is Ganondorf as the main antagonist. Zelda's time - traveling also plays a crucial part. The new abilities Link has are important too, like Ultrahand which helps in building and puzzle - solving.
Impa is often quite popular. She has a long history in the Zelda franchise and in fanfiction, she can be portrayed as a powerful mentor figure. She might have her own backstories explored, like her training in ancient Hylian martial arts and her relationship with past generations of the royal family.
Another plot could be a time - travel story within the fanfiction. Maybe Link gets sent back in time and has to relive parts of his adventures, but with the knowledge of future events. He could use this to change some things, like preventing certain tragedies that occurred in the original timeline, and this would also impact his relationship with Zelda in new and unexpected ways.
You can't really get Castle Story for free. Such attempts might lead to legal troubles and could also expose your device to risks like malware or viruses. Just buy the game and enjoy it without any worries.
The length of the main story in TotK can vary depending on how quickly you progress and how much exploration you do. Generally, it can take a decent amount of time to complete.
One way to get free gems in Castle Story could be by completing daily quests. These quests are often designed to reward players with various resources, including gems. Another method might be through achievements. When you reach certain milestones in the game, like building a specific number of structures or reaching a particular level, you may receive gems as a prize. Also, keep an eye on in - game events. Sometimes, special events offer free gems as participation rewards.
You might find some unofficial and potentially illegal ways, but I don't recommend that. It's best to purchase the game to support the developers and enjoy a legitimate experience.
