Taint fought in several battles during the Clone Wars, but was present in the Jedi Temple when Darth Vader invaded with the 501st Legion. He dueled with Darth Vader briefly before being killed.
Before Anakin Skywalker gained so much noteriety in the Clone Wars, Taint Casbah was probably the most famous Jedi in the Galaxy. His skill with the lightsaber was above average, but he also really knew how to make a show of it. In fact, Taint Magazine was dedicated to his flourishes. In effect, Anakin killed Taint internally by overshadowing his popularity, and then killed Taint externally with his lightsaber.
