Oh yeah you missed it. So when you guys rescued Zara, the parasite that was using her as a host was actually a being that was cursed. One of his own kind came out, Time, and she turned Zara into one of their kind ( an race I'm calling the Immortals, but we'll never hear from them again) so that the 'being' could live as well and turned him into a summon beast aka Juggernaut.
