There's this show I watched as a kid but I completely forgot its name.
It starts with a blond prince that literally only wears blue, sent into exile with his parents who are the former king and queen of the realm and their protective knight that wears a crown of some sort.
The prince's parents were burned down, then him and the knight go looking for around 7 gems, that were in each country, that have powers of some sort.
On the way they meet a green, tanned girl who has a survival instinct and is like the rogue in the game. The enemies are usually anything from big ass monsters to giant scorpions.
