Quests are one of the more challenging aspects of life in 3 Kingdoms. Scattered throughout the realms are many and varied challenges that will test your intellect, challenge your fighting prowess or just plain frustrate you. Each quest rewards sucessful completion with a number of quest points, from 1 to 100 depending on the difficulty of the quest.
Quests can be found anywhere, and in the case of Peerons Marbles pretty much everywhere. The command qlist brings up a list of currently active quests, and qlist <num> will give you some information on an individual quest. Asking for or providing quest info is not allowed, so when you're on a quest, you're on your own (unless the quest specifically says otherwise)
Although no longer compulsary, questing is advised for all players because along with some impressive equipment you can gain from some quests, questing is the only way to become a High mortal or Wizard.
