From Destinypedia, the Destiny wiki
After Traore's conversion into an Exo, he was selected by Clovis Bray I to test an experimental rocket launcher named the Eyes of Tomorrow, which was capable of firing multiple rockets against several targets at once. Traore went through the Glassway to 2082 Volantis to test the launcher against the Vex under the remote supervision of Clovis I and M. Liu. However, the thousands of Vex awaiting him on the other side of the portal quickly overwhelmed Traore. As the Eyes of Tomorrow locked onto four targets, he was unable to fire the weapon only twice before the Vex's Torch Hammers began melting his body and severed his left arm. Traore soon perished due to his severe injuries, and Clovis I refused to authorize his remains to be recovered due to the risk of allowing Vex through the portal while also blaming the sergeant for failing to carry out the test successfully.
