That definitely gives Maul a good frame of reference and he nods. "Ah. I was brought here from that exact day myself." He pauses. "Or perhaps the day before, it was unclear how much time passed aboard the ship before I brought it down." Y'know, just typical Maul things.

"Is the Emperor dead yet?" He asks. That would narrow it down further. Luke seems to have come from furthest along the timeline given how he'd watched the Emperor's demise himself. Oh, what a happy day that had been for Maul to hear that the old bastard had finally been killed, even if it wasn't by his own hand.
