A storm in a teacup

Two figures in dark, hooded attire face each other in a metallic corridor, one with red eyes and a red garment, the other in a black cloak and helmet, before the scene cuts to a long, empty corridor with angular architecture. A man with a lightsaber appears, followed by a dark, shadowy figure moving through a dimly lit area, then a large, mechanical creature with multiple limbs moves through a high-tech room, its body shifting and adjusting as it advances.
