I can't remember much, but these four animated people find a castle and they gain elemental powers.
They then find this girl who tells them to guard a weird looking blue orb. The villains then get to the orb but the orb breaks. The pieces of the orb are then lost and they have to go find the pieces.
I would be very grateful if you guys can find out what this is. I think it was made between 2019-2010.
