Pulled in Two

This is a story for the 100 Themes challenge.

Introduction
When you have a sister in the Dark Forest and a sister in StarClan, especially if they look almost exactly like each other, it's hard to tell what's right and what's wrong.

After the Great Battle, StarClan cats came to anyone in dreams. The Dark Forest was defeated, or so it seemed. But somehow, a Dark Forest cat of an unknown name visited my sister, Goldenwhisker. My other sister, Sunfire, was killed in her strange lust for power. Eventually, she tried to kill Jaggedstar himself, but she thought he was on his last life and was exiled. Apparently, she died sometime while away from the Clans, alone and unwanted. It shouldn't come as much of a surprise, then, when she went to the Dark Forest instead of StarClan.

Complicated
If you though that was complicated enough, then you're in for a bit of trouble. It happens that my sisters look exactly like each other, so I can't tell if I'm meeting one or the other.

It never seemed like much of a problem—until Jaggedstar made me deputy after Foxtooth retired. Being a deputy wasn't the problem, but Jaggestar was on his last life. I would be a leader soon, and then what would happen? I have two sisters, one of StarClan and one in the Place of No Stars. It doesn't really help that they look exactly like each other. It doesn't help at all.

Making History
Yep, it was bound to happen. Jaggedstar died honorably when he drove off a badger but took the worst of its fury. He died later of his injuries.

I remember seeing him the seconds before he died. Time seemed to slow to an eternity as he whispered to me, "Lead the clan well, Stormheart. Earn your place in StarClan, and promise me you'll be remembered for as long as the Clans rule the lake."

My voice shook as I whispered, "I promise."

Jaggedstar nodded as he took his last breath, and was gone.

I shared tongues with him one last time before turning to Lilystem. "I'll tell the Clan that he's in StarClan. Prepare the traveling herbs, because I'm ready to go tomorrow."

I leaped up on the Highledge. "Let all cats old enough to catch their own prey meet beneath the Highledge," I yowled.

All of the cats raced out of the dens or payed attention from where they were in the clearing. "Jaggedstar has died from his wounds from the battle with the badger," I announced. "It is time to appoint a new deputy. I say these words before StarClan, so the spirits of our ancestors will hear and approve my choice." I took a deep breath. "Skywhisper will be the new deputy of ThunderClan."

The she-cat looked both amazed and surprised as she looked up at where I stood. "I never though this would happen," she purred breathlessly.

"You have proven yourself to be compassionate but firm. Not just with Bluetail, but with all of the cats of our Clan."

Skywhisper nodded. "I know what to do. Go with Lilystem and get your nine lives."

Rivalry
Sunfire stared through the pool, the starry liquid that allowed StarClan cats to communicate and see what was happening. Jaggedstar was dead, and she was ready to go through and bring him to StarClan. "Back me up, Flametooth," she ordered, referring to Jaggedstar's brother.

Carefully, she stepped through the viewing pool. She was pulled to the other world, the one where the still-living cats existed. She was about ready to take Jaggedstar's spirit to StarClan when she bumped into Goldenwhisker.

"What are you doing here?!" Sunfire hissed, trying not to be heard.

"The same thing you're doing," Goldenwhisker replied. "We look alike so much, who would notice if I came instead of you?"

"Even in the Place of No Stars, you're scheming," Sunfire complained.

"Yep, and I'm proud," Goldenwhisker bragged.

"No breaks at all?" Sunfire continued. She motioned with her tail for Flametooth to talk to Jaggedstar.

"What better time to spend my afterlife until I fade away from existence?" Goldwhisker retorted. "Now, I better stop getting distracted and do what I came here to do." She turned around, but Jaggedstar's spirit was already in StarClan. "Goldwhisker, you're such a mouse-brain sometimes. I'll get you for this, Sunfire!"
