Final Fantasy V/Tycoon and Shiva

Tycoon Castle
Mount the dragon and fly southwest to the valley where the game started. Fly south, then east, then north over the Tycoon Meteor and continue to Tycoon Castle. Land and enter the castle.

Everyone knows Reina here, so you pretty much have the run of the place, but there is one doorway that's blocked by a solder who insists you talk to the chancellor before doing anything else. Go inside the castle proper to start a cutscene. The chancellor says something about monsters attacking and asks Reina to stay, but she still need to find the king and save the remaining crystals. She agrees to stay the night though. Later, Reina goes for a midnight stroll and finds Faris on a balcony. Reina ask Faris if she really is her older sister, thought to be lost at sea many years ago. Even though it's kind of obvious that she is, Faris denies it with a laugh. The cutscene ends with Bartz being startled out of bed the next morning.

There is a lot to explore in the castle. You start in the west sleeping quarters; exit then go downstairs to a dining area on the 1st floor. Exit south to enter the anteroom, then go north through the double doors to the King's Hall. The are four doors here, but the ones southwest and southeast both just connect to the balcony where Reina and Faris were seen earlier. The northwest door goes to the second floor, with Reina's room on the left and a stairway on the right. These stairs lead to the King's chambers, but you can't enter while the king is gone. Back at the King's Hall, the northeast door leads to a series of rooms. When you reach the 4th floor check the urns for treasure. From the fifth floor you can reach the roof, which is a dead end but you might remember it from the opening cutscene. Go back to the anteroom and take the east door to a library. The woman there reveals that Reina's sister, whom we still insist is actually Faris, was called Salsa before she was lost. Check for goodies here. Go back and then outside. Find the doorway that was blocked earlier west and down some stairs. This leads to storehouse at the end of an alley. Press the button on the wall to open a secret door, then follow the hidden passage to a room where the chancellor is waiting. Talk to him and he gives you a HealingStaff and leaves. The chests here have equipment for jobs you don't have yet, but there's no harm in collecting them now. Go back to the courtyard and search to the east for a path behind a wall. Go east, then north on to a tower, then enter and go up the stairs to reach another storehouse with a few more goodies.

Walz Watertower
Shiva is an optional summon spell you can earn by defeating a boss of the same name. This can be tough if you attempt it too early and it's pointless to do it before you get the Summoner job. To start, return to Walz Castle and get to the first floor by the stairs in the anteroom. The south door on the right side of the room takes you outside; go up some stairs on the right and start wading in a kind of aqueduct above the moat. Follow the stream north to a waterfall and enter its base, this is the secret entrance to the Walz Watertower.

Navigation is simple here, just go up a level at a time until you reach the 4th floor. The monsters here could once be found in Walz Tower, at least until it sunk into the ocean, so you can still get the BlueMage spell Toad Song here if you missed it before. Make your way to the pulsating light at the center of the room and check it to start a battle.

When you win you receive the summon spell Shiva. To exit the tower quickly, find the door in the south wall and shoot down a waterfall to aqueduct where you entered.
