The Three Masters were the three penguins who started the training of Ninjas, and the game Card Jitsu. Like Sensei they spoke in haikus, and had beards.

Background
The Three Masters where not allways friends. For years they argued over wich element was more powerful. They did not know wich was more powerful, because fire could be beaten by water, water could be beaten by ice, and ice could be beaten by fire. Because one could allways beat the other they continued to argue. Then on day, and very old penguin visited them. He told them this.

"Take these cards, and learn the game. Then teach it to others. For those who master it, give them this white belt. As they master it more, give them more belts. Train them until they earn the black belt. You three shall be the founders of the ninjas."

The penguin then disapeared. The three penguins decided to do what he said. They learned the game, and then started to train others. Soon ninjas filled the mountains, and the three penguins had become the first Senseis. Years later they got old and weak. Before they died though, they chose their most trusted student to become the next Sensei, and that tradition has been kept ever since (except in the case of Pen Chi's disapearence).

Involvement
The three masters have died, but their spirits continue to guide the Senseis of today.

Trivia
