Culture and traditions

Hidden Valley is ruled by a monarchy, by a king or queen. In terms of marriage, the king or queen, decides who they marry, even if the other is in a relationship with someone else - as heard when Lilac and Seth had to break up because Antonio wanted Lilac as his queen.

When a king or queen passes away, their other must step down and the crown is handed to the oldest firstborn, or if they do not have any heirs, to the next family member.

Hidden Valley takes after Hispanic, Latin American and Spanish speaking countries. As part of the tradition, they celebrate "Dia de los Muertos", "Day of the Dead".

There is a barrier protecting Hidden Valley which keeps it hidden. It was made generations ago, but it is unknown who made it. The only way to get rid of the barrier to hit it with the power of each element. There has never been a time when all 9 elements were in one place so it's never been done. The barrier is broken after Felix successfully defeats his father in combat and takes over as the new King of Hidden Valley. The barrier is broken by Felix (Fire), Leya (Water), Cloud (Wind), Lana (Light), Cody (Earth), Lily (Darkness), Athena (Plant), Diego (Ice), and Seti using Lightning powers he's kept hidden for years. The breaking of the barrier also revealed Seth's powers over the element of lighting.
