many new players dont know anything of FO1 events so that would be for them, and i didnt say masters follower, i said a descendant of one
have you forgotten those purple robed guys? the Children of the Cathedral, they were masters human followers
1. There are plenty of tidbits and things in New Vegas, that give newer players something from FO1, like Nightkin for example.
2. Like I said, they'd have split up years and years ago, off doing their own thing, after the Master was destroyed. Just like the Super Mutants have done.
3. Look at 2, for your answer to the Children of the Cathedral's outcome. They're not around, with the same beliefs, they're doing other things.
