Grail is designed to provide quest information to other addons to make their decision processing easier. For example, an addon like EveryQuest or TourGuide would be able to make use of Grail's knowledge to determine if a quest has been completed, whether the character can obtain the quest, what reasons the character cannot obtain a quest (lack of level, wrong race, wrong class, not enough reputation, has not completed a prerequisite quest, etc.), the location to obtain or turn in a quest, the amount of reputation awarded from completing the quest, whether the quest counts towards an achievement, etc.

Grail contains an internal database of quest and NPC information that is used to provide its information. The more accurate this information the better the database. Therefore, as the character obtains and completes quests the database is checked to see whether it can be updated. As a user of Grail you can choose to participate in making the database better by providing that updated information to be integrated into future releases.

Starting with version 029, Grail's achievement and reputation gained information are separated into two loadable on demand addons included in the package.
