The Knights of Atlantica are an organization in the Teardrop world, created by Teardrop as the principal Atlantica's defense forces. They are known for appearing in a lot of games since the end of the first one.
The most notable member is, surely, Teardrop. He is the hero of Atlantica, and has defeated evil countless times. He's an oceanian with the power to change forms.
After him is Rufus, the oldest of Atlantica's knights, and a master swordsman.
The third in command is Ayla. She's an Oceanian knight, and the best in defense.
