From Halopedia, the Halo wiki
In 2555, 'Bemet organized a team of six Sangheili who were to meet in an abandoned servants quarters in the Qish'tani region of Tolvuus, Sanghelios. Their plan was to infiltrate a weapon production facility five kilometers from the building and use the weapons they stole to kill Arbiter Thel 'Vadam. 'Bemet held a deep hatred for 'Vadam for making peace with the humans and felt he should die for his betrayal of the Sangheili.
However, 'Bemet's plan failed when one of the Arbiter's soldiers, Usze 'Taham, entered the building and told him that all of his co-conspirators were either dead or captured. 'Bemet and 'Taham engaged in an energy sword fight in which the former fought hard using the 'Anyame technique; however, 'Taham was familiar with the technique and turned 'Bemet's aggression against him, stabbing the rebel in the back after a counter move. Otar's last memory was of his wife Ilta, who had died while attempting to create an incendiary device for use against the Arbiter.
