Ivalice in Final Fantasy Tactics Advance is a dream world and country populated by five races. Situated in a peninsula that stretches southwards, its geography varies from deserts to snowy mountains to lush green plains. The kingdom is governed by a set of laws created using magic by its ancient king and enforced by a rank of Judges.

Geography
The geography of Ivalice revolves around plains, mountains, deserts, forests, and swamps, and introduces areas called jagds; lawless slums where no Judges dare to tread. Jagds are the only places where a character can die; everywhere else, they are protected from death by the Judges and are simply knocked out.

The placement of location symbols on the world map after each story-related mission and certain other missions is controlled completely by the player, and there are potentially thousands of world map configurations varying by player. The "Treasure Hunting" system is deeply linked to location placement, and can sometimes result in items that cannot be found any other way (note: Four locations in the game always have default placement - Giza Plains, Cyril, Bervenia Palace, and Ambervale).

Calendar
There is a calendar system that advances one day for every step taken on the World Map. There are 5 months, and each month has 20 days in it. Each month is also representative of one of the races of Ivalice. If the number of units in the Clan decreases to 5 or less, a mission will become available in the Pub that allows one to recruit a new unit, whose race depends on the current month.

The months are, in order:

Kingmoon - Month of the Humans.
Madmoon - Month of the Bangaa.
Sagemoon - Month of the nu mou.
Huntmoon - Month of the Viera.
Bardmoon - Month of the Moogles.

Demography
Other than monsters, five races make Ivalice their home - moogles, humans, bangaa, viera, and nu mou.

Laws
Main article: Law system (Tactics Advance)
Laws were first created in ancient times by an Ivalice king hundreds of years ago. The king used powerful magics to create these laws, he then established the judicial system to enforce these laws. Only the king's royal lineage knew the means to control these laws.

The laws of Ivalice is governed by a group of Judges who enforce them on behalf of the palace who decide the sequence of laws. Whenever a citizen of Ivalice declares an engagement, the Judges will appear out of nowhere and supervise the battle. Usually, these laws have been set and are not changed easily, and even so they are not difficult to follow. But under Queen Remedi, the laws are frequently changed and have become much tougher, leading to rumors that this is only done to please Prince Mewt. Although they are the object of intense enmity, the citizens of Ivalice nonetheless obey the Judges out of fear of persecution or imprisonment.

There are rumors, however, of a growing underground resistance movement which is reportedly spearheading a rebellion. When Clan wars have become much more frequent, the laws were made tougher. The situation becomes much worse with Ezel Berbier, a Hermetic who created Anti-Law cards to declare his resentment to the laws. While the use of Anti-Law cards were at first outlawed, they became so popular that the Judges could not hope to detain Ezel.

Finally, under agreement with the palace, the Judges, under Judgemaster Cid, have announced its decision to operate as an independent, neutral entity. After this announcement was made, rumors surfaced that about corrupt Judges and Blank Law cards for sale. Some of the laws were so ridiculous (such as the "kissing law") that Judgemaster Cid began to contemplate resignation. The JudgeWatch, an investigative body of the Judges, sent undercover agents to investigate the matter and was finally revealed that the Judge operating the Sprohm prison was the source of the corruption. Judgemaster Cid and Clan Nutsy apprehended him along with his lackeys.
