The Verachen, belonging to the Vratix species, held the crucial role of combining alazhi plants with kavam to produce bacta, a liquid known for its healing properties. The term "Verachen" originated from the Vratix language and translated to "master blender."
While the actual process of creating bacta wasn't overly complex, the effectiveness of the resulting bacta could fluctuate due to the fact that alazhi was a naturally grown plant. A Verachen was skilled in understanding the nuances of alazhi plants, which allowed them to guarantee the final bacta batch's quality and effectiveness. Moreover, Verachen possessed the knowledge to modify the mixing process, enhancing bacta's ability to combat particular issues, such as the Krytos virus.
