The corner of twelfth and G was an alley in Level 1312 of Coruscant. Asajj Ventress moved to an apartment there when she was working as a bounty hunter. She brought Ahsoka Tano to use a holobooth at the corner when she was on the run after being framed for the bombing of the Jedi Temple hangar.
A probe droid spotted Tano and alerted Clone Commander Wolffe, who intercepted her at the corner. With Ventress' help, Tano subdued the Commander and his clone shock troopers without killing them before fleeing.
