Origami Rank 3:
"At the final rank, the Artisan has the ability to create actual animals, fully alive and formed of flesh and bone. The animal may be up to the size of a heavy war horse, and has no real intellect and no magical powers. Therefore, a Ki-Rin would look like a Ki-Rin, but be unable to fly, ingnite itself, or use spell-like abilities. A giant eagle, on the other hand, would be able to fly, because a bird's flight is not a magic power. It is completely under the command of its creator, and has the ability to communicate through barks, nods, or other animal actions. It is not intelligent, and cannot read or understand complex orders. As in her Rank 1 ability, the artisan is not limited to "real" animals - creations from the character's imagination are acceptable, as are animals from myth and legend. It is loyal to its creator, and will risk itself for their well-being. These animals last a number of hours equal to the artisan's School Rank."
Some of the fish they caught were Origami, too. They look like real fish for three hours, then suddenly turn to paper into your stomach. The paper is, of course, laced with poison. Barring that, they had to watch out for the Heavy-War Horse sized origami Tyrannosaurus Rexes that roamed Rokugan, while the Kakita Artisans ruled over the Emerald Empire with an iron fist.
