The Assassination of Ulkesh was a plot devised by John Sheridan to eliminate Ulkesh Naranek, ambassador of the Vorlon Empire to Babylon 5. Following the destruction of three planets deemed by the Vorlon to have been influenced by the Shadows, Ulkesh was confronted at his quarters by Michael Garibaldi and Babylon 5 security. Garibaldi demanded the Vorlon to leave the station due to his governments' actions. Ulkesh attacked and forced the humans to leave his quarters. With Ulkesh gone, Sheridan's plan to face both the Shadows and the Vorlon was safe.
