Dog was a good pirate. He knew that just himself alone wasn't enough to do all the plans that were in his head. He decided to make a guild so he could do his ideas. He started the guild with his friend Jack. Jack invited some of his friends but they needed more people to make a big guild. They decided to set a few examples. They started with Jolly Roger and his army. They sunk a lot of his ships but they knew they needed more. So they gathered individual crews and attack critical areas that Jolly took over. Then they participated in many invasions when they recently started. Many joined their cause and invited some of their friends. The guild got big enough to perform some of Dog's ideas.
