The Shinarcan Bridge Extension Skirmish transpired in the hours following Order 66. In this event, the 501st Legion launched an assault on several Jedi attempting to covertly evade security protocols on the Shinarcan Bridge Extension.
Etain Tur-Mukan, a Jedi Knight, found herself present, endeavoring to blend in as a mere observer while attempting to escape Coruscant with the aid of Kal Skirata. As the conflict unfolded, Etain reacted instinctively, intervening to safeguard a clone trooper from a fatal blow from a lightsaber, using her own body as a shield. Witnessing this act and her subsequent demise, Kal, accompanied by Omega Squad, became enraged and redirected his aggression towards the Jedi, assisting in the elimination of several. Furthermore, Niner, a clone commando, sustained significant injuries during the engagement, which resulted in the deaths of all the Jedi present, or their forced retreat.
