Dungeon

Dungeon (ダンジョン, Danjon) is any type of adventuring location in all MMO games. YGGDRASIL was mechanically known to contain various dungeons for such players to challenge.

Overview
In YGGDRASIL, dungeons are areas that players can enter to do some grindings, leveling up and acquiring items. On the other hand, dungeons are also conquered by a guild or more. It can then be made into a guild base controlled solely by the guild alone for other various means like customization, etc through the use of Data Crystals.

Rules
While dungeons may be look as seemingly impenetrable and impossible challenges, they are quite to the contrary. Possessing a dungeon is a great undertaking that seems like only a powerful guild can manage. Once occupied by the guild, the design, defenses and appearance of a dungeon could be altered to suit the needs and taste of the players.

However, in order to achieve this, several factors need to be included, such as necessary skill in programming for making alterations in the area; sufficient data crystals to adding additional features; and even gold to finance the special effects of areas. Additionally, another factor that also needs to be considered for a guild to rule a dungeon is to ensure that it must meet the specified laws enforced by the programmers and administrators of YGGDRASIL.

For example the Ariadne System, a game system embedded in YGGDRASIL, that checks the validity of a created guild base. There must be a path that leads from the entrance to the heart of the base. Other things, which the Ariadne System inspects further is the distance one could travel inside, how many doors, and rules on base constructions that were set in detail. As a result, dungeons that violated the rules would be flagged by the YGGDRASIL system and fined. The Guild funds would then be deducted gradually at a visible rate.

Trivia
