they create the adventure, control the NPCs, and narrate, for the most part. in smaller groups the DM will sometimes run a character to fill in a gap in the party, and sessions usually revolve around the DM's schedule.

it's also up to the DM to design dungeon layouts and encounter areas.

a good DM wil only use their absolute authority hack when a player is trying to cheat or to make things more interesting by adding new challenges that are not part of the basic rules.
