A long overdue briefing
"What am I looking at?" Jack Ryan asked as he walked into the situation room: the main screen showed a satellite image of a huge crater, "Please god tell me it's not another nuke!"
"No sir, it's worse than that." A young army officer came to attention, "Captain Riley Finn, Special Operations, Sir."
"Talk to me Captain." Ryan took his seat, "Where is this?"
"Sunnydale California. And it's not a nuke, it's worse: it's a Hellmouth."
"A Hellmouth. Didn't you get that briefing?"
"A Hellmouth is, like the name implies, a gateway to hell."
