Here it is: by popular demand, I guess, the epilogue to Slayers and Sixth Years. Please note that since I'm writing this epilogue, there won't be any sequel. There wasn't a plan for a sequel anyway, but look out for the SASY prequel, AWA, coming soon.

After it was over, everyone had to take stock of what was left of their lives and rebuild, or start anew. Things would never be the same, obviously, and in most cases, things would never be easy or innocent again.
Craig's body was pulled out of the masses Slayers looking for survivors. He'd died with the same smile on his face. At his funeral, Dumbledore spoke of how he was now with the only person who he'd ever really cared about.
Dumbledore was asked by the public to become the next Minister of Magic. This time, to avoid another unfortunate experience of the likes of Cornelius Fudge, he accepted. One of his first actions was to move the Ministry from London to Hogsmeade, so that he could keep a closer eye on Hogwarts. Six years after becoming Minister of Magic, Dumbledore had a stroke and died.
Buffy and Giles settled in at Hogwarts in new accommodations built on the battlefield. They set to work rebuilding the Watcher's Council in peacetime and eventually built a completely new training complex for the Slayer's in the Forbidden Forest. Both Buffy and Giles lived long, healthy lives, and died of natural causes.
Faith and the rest spent the rest of their time aiding Buffy and Giles in building up the council. Faith took Xander and Andrew and set up a foreign office for the Watcher's Council in LA, with the assistance of Angel and Wolfram and Hart. Faith lived to the age of thirty-nine, when she was killed by a Fyarl demon.
Wolfram and Hart turned out to have evil intentions for Angel his gang, of course, and after a few months of bloody struggle between Angel's faction of the firm and the loyalists, Angel won out and destroyed the Senior Partners, giving him full, unhindered control of Wolfram and Hart. This all happened long after the deaths of the humans involved in the battle for Hogwarts.
Ginny Weasley eventually graduated from Hogwarts School of Witchcraft and Wizardry. She never managed to get over Harry's departure, not completely, and chose to take a posting as Slayer in a nameless foreign country. She died there, victim of a vampire attack, at age twenty-two.
Ron Weasley and Hermione Granger married shortly after leaving Hogwarts. Hermione took a job teaching at Hogwarts, and Ron became Dumbledore's personal assistant. When the old man died, Ron succeeded him as Minister of Magic, with lots of help from his wife, of course. Despite several assassination attempts, Ron and Hermione both lived well past a hundred, spending quite a bit of that time guarding the magical world against further insurrection.
Harry Potter left Hogwarts the same day he saved the world. He roamed the world for a time, unable to figure out what to do with himself. Eventually, he went to LA to fight the forces of evil with Angel at Wolfram and Hart. Two hundred years later, when the apocalypse was nearly brought on by the Senior Partners of Wolfram and Hart, Angel achieved his redemption and was turned into a human. He died sixty years later, leaving Harry in charge of Wolfram and Hart.
And to this day, Harry Potter, the Boy Who Lived, fights evil as a vampire with a soul.
