Forgotten Capital | Disc 1
As soon as you enter the Forgotten Capital, you will reach a fork in the road that splits off in three different directions: one to the left, one to the right, and one in the middle. Start by taking the pathway to the left.
Follow the pathway along until you reach the first house on the left side of the screen. You will find a 
Save Point inside and a treasure chest on the second level that contains a 
Magic Source.
Continue traveling to the right of this house until you reach the Forgotten City with the spiral staircase.
Forgotten City
Travel down the stairs to find a treasure chest that contains an 
Aurora Armlet. The Armlet is a strong piece of Armor that you should equip on the character who takes the most damage, typically the one holding the 
Cover Materia.
Return to the entrance and, this time, take the pathway leading to the right. Take a right at the first fork in the road and enter the house that looks like a shell on the inside. There is a treasure chest at the top of this house that contains a Guard Source.
Proceed down the pathway until you reach the next fork, which leads to another house. There is a treasure chest on the bottom floor that contains an Elixir.
Climb the ladder to the second floor, and a prompt will pop up, giving you the option to rest your characters and refill their HP and MP. Choose to get some rest to continue the story and then continue up to the top of the house to find an 
Enemy Skill Materia hiding behind the top bed.
There is nothing any further down this trail, so make your way back to the three-way intersection at the entrance to the Forgotten Capital. Proceed down the middle pathway to the north.
Enter the building behind the lake and grab the 
Comet Materia at the top of the building. “Comet” is a powerful magic spell that is strong if you have any characters focused on using magic attacks in battle.
Make your way down the blue set of stairs in the middle of the house, which lead downward (use the screenshot below to help you find them).
Water Ring (Reminder)
Helpful Hint
Before you descend the stairs, you should make sure that one of your characters has the 
Water Ring that you picked up in the Corel Valley equipped in preparation for an upcoming boss battle.
Continue down the glowing staircase towards the castle at the bottom. Use the Save Point at the bottom of the stairs before you proceed, as you may wish to come back to this part of the game.
Walk towards the steps at the bottom to continue the story.
Spoilers!
Warning
Do not scroll past this point until after the boss battle, as there are spoiler images below.
Boss Battle
HP: 10,000
Reward: Wizard Bracelet
All of Jenova·Life’s attacks are water-based, which means that as long as one of your characters has the Water Ring equipped, they cannot possibly die.
Aside from that, it’s just a regular battle. Jenova·Life will cast Reflect at some point in the fight, so be careful about relying too heavily on magic-based attacks. You can also use your Destruct Materia to remove the Reflect spell by casting DeSpell on her.
A video demonstration of this battle is included below for reference:
Several additional scenes follow the Jenova fight, marking the conclusion of the first disc. The game will give you the option to save your game file before proceeding (which is a good idea). Click next to proceed to the next section of the strategy guide.
