Dragon's Dogma will feature a dragon so big, so dogmatic (why not) that it'll take the collective efforts of everyone playing to kill it. The "Ur-Dragon" is an event in which every player party will be able to fight the giant beast in their own games, with all damage dealt to it worldwide contributing to the depletion of its health.

The person to strike the final, decisive blow will get the "maximum reward," but players who cause damage will also receive item drops. Of course, if hacking away at a big old dragon weren't rewarding enough on its own, nobody would ever play Dragon's Dogma.
