The Battle of Druckenwell was a battle fought during the Yuuzhan Vong War in 26 ABY on Druckenwell. During their campaign to cut off the Corellian Run, Druckenwell was among the countless conquered worlds including Rodia, Kalarba and Nal Hutta.
The New Republic was able to evacuate most of the planet's population to Duro where SELCORE was operating a terraforming project to make the planet green and habitable again. However, they were not able to prevent the Yuuzhan Vong from conquering the planet. The alien invaders then began terraforming the planet to suit themselves. The aliens also managed to capture a Force-sensitive Cerean by the name of Ka-Tu-Un whom they mistook for a Jedi Knight.
