After fighting the dragon.

Lightning enters the cave with 3 other caves, after fighting the dragon he dropped a scroll it said:

There are 3, one with riches, one pain and one with the one you seek. 

She figured that the caves aligned with the order of which they came in the scroll. She know not to go with riches. So she wrote a big X on it. The other 2 were hard. She thought 'the one you seek' would be her sister, who was dead. She Xed that one too. So she went through the 2nd one.

There was a soft light coming from within the cave. 

"Hello young one." A old voice came out in gasps       

"Hello?" Lightning said her voice being Echoed "eloo eloo eloo."

"Come in."

"Umm... Okay?"

Lightning padded in to the cave Lit with lanterns all over the cave. Has she looked closely, she saw a male WindWing.

"Hello, I'm Stormchaser. Good job."

"Thanks, I'm—" Lightning started.

"Stop right there. I know your name, Princess Lightning." Stormchaser said. 

"Okay," She looked around the room. "What do I do?"

"First, get your bracelets." Strormchaser pointed at a tunnel across the cave. "Then come back to me."

Lightning quickly grabbed them and came back.

"Good, Now the test for strength." Stormchaser flew up in to the sky on to a ledge; Lightning followed. "Make a storm."

Lightning thought Storm, Storm, Storm, Lightning Storm, please! The storm came with a loud CRASH! 

"Good. Now get rid of it."

Now she thought Go away storm I don't need you any more. Please. It soon went away leaving the hill peaceful again.  

BUT NOT FOR LONG...
