Oops, you found a dead Link!

It would seem that the princess is in another castle!
Possible reasons for this include, but are not limited to:

1. The princess has been moved from this castle to another one.
2. The princess has been deleted.
3. The princess is somehow lost forever!
4. The princess never existed in the first place and your entire adventure throughout Hyrule has been an LSD trip this whole time! 🤫
