Bravely Default/Chapter 4

Upon touching down on Eternia, Edea explains that the Earth Crystal is in the Everlast Tower, which was formerly known as the Temple of Earth. To get there, you must first survive a trek through Frostpeak Passage.

Frostpeak Passage
The nearest gate to the city of Eternia is closed, so you must take the dirt path around it. It is here you will be introduced to the various enemies you'll find across Eternia. Silver Wolves can inflict paralysis with Paralyzing Bite, while Mandragoras attack in groups and can poison you with Poison Pollen. Teufels sometimes appear at night, and possess the powerful Thundaga spell.

Boss: Ice Golem
As you near the city, you'll see a massive monster in your path. Approach it to start a fight with the Ice Golem! The Ice Golem is a simple boss, but a very powerful one at that. The threat comes from its strength, able to dish out incredibly painful attacks including its abilities. Freezing Punch is an extra strong move that has a chance to inflict Stop, a nasty status ailment that can potentially ruin your team strategy. It also has Blizzard Blast to strike the whole party with.

As with most minor bosses, the Ice Golem does not require a very sophisticated strategy to beat. A healer is important as always, given that its attacks are extremely damaging. Stop is a major consideration as it is hard to defend against, and hard to cure. Since all the boss's attacks are physical, Ninjas can be very effective against it using a combination of Utsusemi and Transience. You can also try to Blind it, which will render its attacks nearly useless against your whole party, although your means to do so are limited outside of Specials.

With the Ice Golem out of the way, head north to enter the city of Eternia!

Eternia, Land of Immortality
At the city, Edea explains that the Eternia is connected with a system of white magic cables, using its energy to treat various diseases. One of Edea's old friends tells her that Edea's mother has fallen sick, and is currently being kept in the Central Healing Tower. Perhaps you should pay her a visit. Go into the entrance with the yellow light to enter the Central Healing Tower, then go to the top-left corner of the building. Edea's mother, Mahzer Lee, has heard about Edea's betrayal from her father, but bears no ill will to the group. She only wants Edea to talk it out with her father.

After the cutscene, check the top right corner of the room for a Rebuff Locket. Outside, Edea reveals that the white magic cables get their energy from the Earth Crystal, and ultimately decides to help awaken the Earth Crystal despite the impact to Eternia's patients. She says that there are three paths to Eternia Central Command, where the Council of Six are stationed. The center path is the shortest, but has very powerful enemies, the west path is longer but the enemies there are more manageable, while the east path is the longest and lacks any strong foes.

Before you set out, take a look around Eternia to prepare for the trip. In front of the exit to the Central Healing Tower, go west and search south to find an Elixir. Go to the southeastern corner of the city and inspect the area to get an Artic Wind. As for the shops, there is a wide variety of weaponry to be found in the armory, while you can get level 5 White, Black and Time Magic from the scroll shop.
