Eeh, Zamarca, who is that?
This is what happens when people see one of the dragons with a rare scale color. The rare colors are gold, silver, and multi-chromatic colors.
When a dragon with rare scales step into the room, even if they are in their bipedal form and that form is made to look like they were a dragon with common colored scales, every person in that room that sees the dragon will feel a rush.
This rush is different for different people, Some people feel a rush of excitement, of happiness or a need to be friends with the dragon, while others liken it to a rush of sexual attraction.
Some scholars say that the force and length of the rush also depend on the color. A Goldrush, that is to say, a rush you get when encountering a Golden dragon is the strongest one.
