Runes or loose symbols appear on the dergon’s body, with an optional ‘shadow’ or gradient underneath them and an optional glow effect in the same color(s) as the marking. The runes themselves  can be thicker, like separated maze-like markings, or thinner, like letters. Runic should NOT be made of any real world script, although a loose resemblance is allowed. Real world non-alphabet symbols should be kept to a minimum.
