Elsa and Ingrid hiked up a large mountain. "Where exactly are we going? I can't leave the castle for too long, I do have important work to do." Elsa looked up at the top of the mountain. "The cave of Bald Mountain should be close by." Ingrid held a hand to Elsa's shoulder. "Bald Mountain? You're trying to work off your pain by taking the forbidden treasure?"
Elsa shrugged. "I'm not really one for treasure. Not in the traditional sense. What I'm looking for is far more important than some jewel. If my research is right, it will have the power to fully vent my anger." Ingrid held out her arms. "Whatever that treasure is, you know that thousands have tried to claim it for their own fortunes, but none have survived the guardian." Elsa held out a hand, forming an oversized snowflake. "That's because none of them are as powerful as the two of us."
The two entered a large cave, only to find a sleeping boar creature. Ingrid whispered to Elsa. "That's the beast that guards the forbidden treasure? Doesn't look that frightening." Elsa looked down at the countless piles of skeletal corpses. "Said probably every single person to come here."
Ingrid picked up one of the skulls, trying to see if the treasure was hidden in the pile. The boar immediately woke up and exhaled a massive stream of flames. Elsa and Ingrid quickly turned around and held out their hands, a stream of ice bursting from each palm. All four ice streams pushed back the fire stream into the boar's mouth, shoving it back into the wall. The impact caused the monster to transform into a human being as a dagger fell out of his cloak.
The robed figure stood up and grabbed the dagger, his whole body bursting into flames. Ingrid threw a massive snowball at the robed figure, knocking him back and throwing the dagger out of his hand. Elsa picked up the dagger, ran toward the robed figure, and stabbed him with it. The man held his hands to the dagger. "You've beaten me. But at a great cost." Elsa looked the man in the eye. "There's no need for theatrics, Gorgon the Invincible. You get the peace and quiet you asked for, and I get the one thing you treasure most." Gorgon fell to the ground.
Ingrid looked around. "There's nothing here. All these people gave up their lives for nothing." Elsa chuckled. "They thought they were chasing gold and diamonds. The real treasure..." Elsa turned around, her face covered in golden scales with bulging yellow eyes. She held out her hand, creating a puff of dark smoke that morphed into the dagger while simultaneously turning her sparkling blue dress into a black leather trenchcoat, her braids disappearing. "...Is this dagger."
Elsa turned the dagger around, revealing the name Gorgon engraved in it, morphing into the name Elsa. Ingrid backed up in fear. "What have you done to yourself?" Elsa sheathed her dagger. "Excalibur was forged of two halves. The Light, and the Dark. When it was broken, the two sides were equally divided. Rumplestiltskin may be the Light One..." Elsa turned around and clenched her fist. "But now I am the Dark One. Now I have the power I need to punish the man who killed my sister... and everyone and everything he knows and loves."
