Strider is just hanging out at the pub and the midgets show up.You should maybe read a little more about the universe and things at play. Most things you ask are dumb to anyone a little more knowledgeable about it.
It wasn't a coincidence Strider was there, for example, or your misconceptions about the Balrog.
I could explain it to ya but you were mean to our sweet @Shinkicker.Strider is just hanging out at the pub and the midgets show up.
The balrog happens to show up in a dwarven relic that has been overrun by orc and Goblins, that he's obviously not in league with as they are all scared of him and run away
