So I haven't played the raid myself yet, but I couldn't help but watch streams of it. So after you defeat Calus you find out that you actually didn't kill him, only a Calus bot. But Moments after you are congratulated for defeating him and are given an invitation to seek Calus out to yet again, "grow fat from strength." What does this new invite provide? And what's Calus's intent to have you seek him out?
