There is an urban legend about a secret dungeon in LINK VRAINS. It's packed full with dangerous traps. And what waits at the other end is...
When you saved me, I could envision 
my brother growing strong like you.
Als du mich gerettet hast,
Cuando me salvaste, imaginé
a mi hermano tan fuerte como tú.
Quando você me salvou, eu via
meu irmão sendo forte como você!
