Narthex Antechamber

C-3PO ordering guards to the Narthex Antechamber

"My mistress requires your presence in the Narthex Antechamber at once."

The Narthex Antechamber was an apparently nonexistent room within Krax's castle.

Around 5.5 BBY, C-3PO sent off two guards to the Narthex Antechamber in order to assist his mistress, Stigrit Krax. However, this was actually a ruse to steal a speeder bike and rescue R2-D2 and Larka Nimondro. While the guards did not know where or what the antechamber was, they did not allow the droid to know and went off in search of the room.
