It was a small, poorly lit place

It was a small, poorly lit place. The walls were lined with scrolls of every kind. Azula walked on until she found the section labeled: Bending History. She was looking for something that could bring her brother down once and for all. She scanned the shelves until something caught her eye. She took the scroll down and read the title. It was called: Dark Bending Techniques. That was exactly what she needed. She slumped down to the floor and began to read. It said:

For centuries, humans have been bending the elements water, earth fire and air. It was a powerful form of art that was truly a gift. Later on, people began to discover new forms of bending. This included, but was not limited to: Swampbending, Plantbending, Sandbending, and Lightningbending. Yet people who wanted power abused the gift of bending, and created what is now known as Dark Bending.

Waterbenders were the first to create a dark form. Using the knowledge that any liquid could be manipulated by bending, Poisonbending and Bloodbending became a reality, and not just a cruel fantasy. Poisonbending was very odd. One could bend the harmful fluid into the body by way of the pores, thus killing the victim. Bloodbending is the method of bending the blood in the human (or animal) body to control the subject's actions.

Earthbenders also use Dark Bending. Though not as creative as the Waterbenders' tactics, Earthbenders were able to maneuver the earth into quicksand to suffocate someone.

Most people looked at the Air Nomads and thought of happy, loving, non-violent citizens. These people were wrong. Yes, the Air Nomads can be great people, but deep in the Air Nation lay the bones of many cruel rulers. One of the worst forms of Dark Bending is what many call Breathbending. An Airbender could take the actual oxygen from the lungs of an opponent.

Firebenders have already been known to kill with their element. Killing with lightning was also common. But most people don't know one of the most ancient forms. It was also the most creative. It is so rare, in fact, only the past Firelords and few Fire Sages know about it. It is identified as Aurabending.
