Really old fic set in season 6. The only thing I remember is Xander deciding to fill out a resume for Buffy without her knowing. Pretty sure it pisses her off for interfering.

Hi there,
I think I have found your story;

The Call by Mefiant

Set forty years after 'The gift'. A call is sent out and those who answer it could change the world they know. But is the price worth it? ? AN: Thanks to Always_jbj, my beta for this fic, who has been listening to me to talk about this one for awhile and has nagged me into starting it. Thank you and **squishes** to Selene2 for the beautiful banner!
