Aerek's scan of the area through all of his senses reveals nothing in the immediate area, though there is a strong sense of danger in the distance. You can see nothing, and it is not urgent enough to be of worry for the exact moment.
Master Kanas' voice snaps through the comlink barely after Aerek had finished responding to the signal, and the old Jedi Master's voice is an almost whispered growl, "What in the name of the Force did you do? I heard some roar about a minute ago and now the whole place is a glowlamp!"
As he spoke, you could all see movement near the wall. Coming from the direction that Skyka and the others had spotted an open gate was a group of four thin, shining figures...it took another moment but it was not hard to identify them as the same model of Sith War Droids as the ones you had previously encountered across the planet. They moved across the clearing before heading almost straight for you. But when they got to the treeline, they stopped and looked down...examining the large body of the 'human' you took down.
