PHASE 21 - HOW I MET YOUR MOTHERS
"The Black Cross Legion will have a large-scale raid against the Dark Legion's headquarters two days from now. And that will be Aeternos... ahem!" The Fake Outsider coughed and cleared his voice on purpose. "...your debut. You will take part in one of the largest battles of Gate Guardian history."
"If the Phoenix Incident will happen, then I should avoid taking part in it," I said. "I'll just sneak in the Underground Laboratory after the raid."
"No, the raid is the only chance you'll ever get to see the God Core of Chronos. You can't do it before the raid, because it is swarmed by Cursed Guardians. After the raid, the Black Cross will completely lock the place down. You don't possess the God Core of Freyr nor the <Heart of Light> anymore. You're just a normal Gate Guardian. I reckon you can't take a horde of guards in that state."
