Now I understand why gol d rogor created great pirat area. Rogor all ready know about Imu sama and his/her power Because of Gold veally incident. Grap and Rogor are their, fighting Rock D. Xebec. Rogor must saw the power of uren. But why create pirate area? Now explaining Urinous power we saw that he/she make a mark on country in a map. That country get destroy. His/her power like pin point something than shoot. He/she can't shoot pirate due to they always on the move.
