Alternate Everquest

The first group to the instance, and kills one NPC claims the right to the instance so long as that group consists of 6 characters and can maintain 6 characters. Should you drop below 6 characters due to people leaving or disconnecting a 30 min grace period is allowed to fulfill the group (Better show proof if you intend to take a zone from someone else, and it better be concrete). If one or more can not be found you run the risk of forfeiting the zone to another group that is 6 people. Be kind to one another. Bosses have been known to have heart attacks if people cant get along.
