Final Fantasy II/Mission to Mysidia

The time has come for you to visit the town of Mysidia. To reach it, you must travel south from Fynn, and then follow the stretch of land that travels west for a bit before continuing south. Travel all the way down until you cross a river. Mysidia is nestled into a mountain range that runs from southwest to northeast. Be careful, however, as the land around Mysidia is home to some of the strongest overworld enemies that the game has to offer. If you haven't been strengthening your team, travel to Mysidia will be quite difficult. You will want to have your ship nearby, so it's a good idea to sail as close to Mysidia as you can from any direction. As an added benefit, it will cut down on how many dangerous enemies you will have to face.

Mysidia
Mysidia is home to a clan of powerful mages who are very informed about the world and its secrets. You will learn a surprising amount from its citizens just by talking to them. For one, you will learn that Minwu was there, but recently departed for Mysidia Tower. You will also learn that in addition to the two masks, you need the Crystal Rod in order to enter the tower. Another mage informs you that you can find the Black Mask on a small island somewhere in the middle of the sea.

However, the most informative location of all happens to be a small house near the souther edge of town which contains a bookshelf. If you walk up to this bookshelf and interact with you, you will have the opportunity to inquire about any key term you have learned. For example, you can learn that mages feared the power of the Ultima spell, so they sealed it within a great tower. You will learn the way to utilize both the White and Black masks. You can even ask it about Dragoons and Wyverns, as well as the Goddess Bell and Sunfire. Learn as much as you can before leaving the building.

The shopping in Mysidia is some of the best that any town in the game has to offer. In addition to having very powerful armor and weapons, it boasts a spell shop with five counters, each offering four spells for purchase. One counter in particular offers four very powerful spells that are found nowhere else.

Tropical island
Your next destination is the small island in the middle of the ocean that one of the mages in Mysidia mentioned. Finding it without viewing the World Map by pressing is considerably difficult. One easy method of finding it is determining the position of Salamand on the map, and then traveling due north from the coast of the snowfield above Salamand. Once you reach the island, there's nothing else to do but step into the cave.
