Clinton asked me to elaborate so I will. This apporach is tailored to Everway and wouldn't be applicable in many other games, unless those other games used Drama, Karma and an interpretive Fortune mechanic.

Basicly there is one GM who fills the standard GM chair.
Another player is the Seer. This player's job is handle action resolution. This is sort of a failsafe against GM railroading without giving players metagame things like "story points."

In essence the Seer takes the Arbitration role of the dice while the GM handles the Mediation.

It's like the standard since GM approach except with human dice.
