It didn't depend on the views of good and evil, but how you used the strength from within.
And as soon as she grasped this thought, another voice came to her; it seemed to speak to her heart instead of her mind. Then it was no longer talking, but singing:
"I was all alone...no one there to guide me through the darkness...of my heart..."
"My song?" she whimpered softly. The pool of blood beside her began glowing, and she looked down at it once more. Cloud was playing her piano in her room and singing:
"I once reached for you, and your fingers left mine..."
"Cloud," she whispered and touched the surface of the blood lake. The image rippled, but did not fade.
"I was all alone..."
"No," she shook her head. "I won't let you be alone."

"Tear my heart open; sift through my memories: Who Am I? Lift all the masks away; come face to face with me: Who Am I?"
Tifa's voice suddenly rose above his:
"Please, come back to me...I sit as a scared child in the black...of my soul..."
And to finish it all, the Phoenix's enchanting whistle echoed their voices in sync:
"Steal through the night and discover, beside me forever...Who...Am...I?"
She had been watching Cloud's profile–the pain on his face, the tears in his eyes; she had never seen him cry. But as the song ended, his image withdrew back into the depths of the blood lake.
"NO!" she shrieked and dove into the dark liquid. As she went under, panic clutched at her chest. What was she doing in here! Cloud wasn't at the bottom–he was in the Outer Realm with the others! She envisioned them all one by one: Barret, Yuffie, Nanaki, Cait Sith, Vincent, Cid–all crying, all missing her. And Cloud...something other than determination burned within him. Something beside the evil dwelt inside him and was ripping at his heart...
"Tifa... I love you."
Tifa's eyes shot open and she looked through the murky substance to the bottom where something was glowing. She focused on it; latched onto the fire that had suddenly exploded within her soul–Cloud loved her!
She dove closer to the light. 'No matter who you are, Cloud, I always want to stay with you! And not even death can separate us anymore!'
"I'm going back!" she screamed aloud into the darkness. The light suddenly shot up and enveloped her in a spiral of glowing energy. Her profile shone red as something within her shrieked and rose from the depths of her subconscious The lake of blood disappeared and she lunged toward the gateway between the two worlds as if on wings. She passed through the archway and tumbled down from the ceiling of her room, slamming onto her bed.
Tifa Lockheart's body twitched and she opened her eyes. Sitting up slowly, she looked around her room. Down at her feet were a pair of mako and crystal gloves. There were four holes in the wall beside her bed and a familiar reddish-gold materia in her hand. The others had been here, but why was she alone now?
A bright flare of gold light exploded from the orb. She felt a sudden flame torch in her chest. Then it was gone as quickly as it had come; she remembered what had happened–now they were probably searching for Damien. She stood and grabbed the new gloves–the Prism Gauntlets–and put them on. Power and magic flooded through her arms and spread down the rest of her person. Her head cleared and her vision sharpened. It was time to go. With a last look at the piano, where Cloud had been singing, she ran out of the room.

Cloud Strife got down from the golden animal's back and placed a hand on its beak. Kinto warked and nudged him forward. Cloud looked back at him, then to the dark cave entrance. The bird had taken him to a remote island way on the upper right-hand corner of the world map; Cloud had only been here once before–to get the Knights of the Round summon materia. Now he stared at the cave entrance and wondered why Kinto had brought him here. He took a few steps forward and the chocobo warked very loudly. Cloud jumped and stumbled into the cave. He glared back at the gold bird and it called to him happily, then turned and left. Muttering curses, he continued through the darkness and into the dimly-lit cavern.
It was just as Cloud remembered: empty, glowing surreally from a spot of energy buried in the ground. He walked around the glowing point in the dirt, inspecting it carefully. Something else had taken form beneath the earth...and it wasn't a materia. Curious, he knelt beside the light and touched the ground. A sense of power quickly surged through him and Cloud instantly knew he had to have whatever was under there. He cracked his knuckles and dug his fingers into the dirt, feeling burning hot metal at his fingertips. He labored over the spot for a few minutes, finally uncovering the top half of what looked like full-body armor. Curling his fingers around the shoulder pads, Cloud gave a heave and the entire thing pulled up from the ground, making him fall backward.
Rubbing his back, he sat up and held the armor out in front of him. He had been right; it was full-body armor–bright yellow-gold chest plate, shoulder guards, gauntlets, and a new plate belt. He brushed the dirt off the glittering surface and turned it over. There was something inscribed on the back plate:
"Good and Evil may die–Power will always remain."

"We didn't find anything!" Yuffie Kisaragi wailed, plopping down on the bed in the room. Cait Sith shook his head and leaned against the wall beside her. Vincent Valentine stood by the window, looking distant. Barret Wallace was stomping around impatiently.
"I don't think there was anything to find," Vincent shook his head.
"I can't believe this!" Barret swung his fists through the air. Cait Sith sighed and held up his PHS device.

"Anyone wanna call the others?"
Suddenly, the mechanism in his paw crackled and rang shrilly. Everyone jumped and turned to stare at it.
"Guys!" it was Cid Highwind's voice. "Is anyone #in' listening! We need help! Damien's here, and he–"
Vincent grabbed the PHS: "Where are you!"
"Right outside Midgar; near the Chocobo Farm! Look, you have to hurry–the &# found us! We can't hide for much longer!"
Red XIII's voice abruptly shot above Cid's: "He's here!"
The device clicked off. Vincent switched it on again, but heard only static.
"Cid! Cid!" he shouted.
"We hafta go ta Midgar!" Barret cried. Yuffie and Cait Sith leapt to their feet.
"That's insane!" Yuffie gasped.
"We need Cloud!" the mog-cat cried.
The PHS crackled again: "Vincent! Was that Cid I just heard!"
It was Cloud.
"Yes, it was," Vincent replied. "Where are you!"
"I'm headed in that direction right now! Get there as soon as you can!"
"Right!"
The transmission clicked. Cait Sith lowered his ears and laughed nervously.
"Well, what do you know?"
"Let's go!" Vincent swirled his cape and ran from the room.
"He says it like it's so easy to run to instant and painful death!" Yuffie wailed.
"You keep forgettin'–he's already dead," Barret growled and ran out after him.
"Oh, that explains it!" she rolled her eyes and darted outside.
"Man...what's my fortune-telling have to say about all of this!" Cait Sith sighed and chased after her.
