Emilia Grey:
As Emilia is a little fuzzy on the specifics of that; as i'm sure the world is since anyone there are the time would be dead but this is my gathering of the events,
Everything follows the last episode of Season Seven up until spike is about to explode.
He doesn't give the nice long warning... (along with the longest dusting in slayer history) he just goes poof and the school sinks into the ground but NOT the rest of sunnydale,
Questions:
How did Annabelle survive, cos she was killed in said episode
Why didn't the rest of sunnydale go down?
How many turokan are we looking at?
1)Annabelle actually died before the final battle in episode 7-10, Buffy later buried her body. As Michael indicated, her first appearance in the game was her crawling out of her grave. Her resurrection was a side effect of Willow's spell.
2)In the game, Spike's amulet had a slightly different effect. The first was banished to another dimension, but Sunnydale didn't sink into the ground. You can read the first post of episode 1 for a recap of how things ended diffently.
3)As of the end of the episode 1, there was somewhere in the neighborhood of 50 Turok-Hans left minus the ones destroyed since the game began (those were the ones that made it above ground when the amulet activated, most were destoryed by the amulet effect).
