Back in Equestria at night all the ponies were sleeping the night away. For today was a busy day for them. But in the Everfree Forest a lake started bubbling and the water began forming into the water demon Wallow. He crawled out of the water and headed out of the forest and into Ponyville. He looked around trying to see where he can snatch a victim and threaten the Main Six to bring the contract of San Venganza. But so far there was nothing.
"So this is Ponyville huh? Nice town. But doesn't have exactly what I'm looking for. I need someone that I know they'll just beg to save. But who?" Wallow thought.
He thought about it for a while til something caught his attention. He noticed a distant kingdom not far from Canterlot. Seeing it had a crystal-like appearance, it appealed to his liking and he smirked as a plan formed in his head.
"Nice castle. Yes I know what to do. I will simply kidnap the queen of that crystal castle and bring her to Blackheart. Once the Main Six and Spike see and hear this they will have no choice but to get the contract of San Venganza. This will be perfect." Wallow said.
So he began walking in the direction of where the crystal castle is and when he spotted another lake be jumped in and swan his way there.
After a few minutes, he jumped out of the water and found himself at the entrance of the Crystal Empire. Evilly chuckling, he walked past the gates and prepared for what's about to come his way. Suddenly, the Crystal Guards ran toward him with their spears raised. “Hold it right there! Freeze!”
"I don't think so foolish mortals. In fact you all are about to be soaked." Wallow threatened.
So using his demonic water powers he washed away all the guards and left them drowning as the demons in the puddles carried them to the deep as they screamed.
Thus, he walked his way up to the crystal castle and entered the palace. The guards were alerted to his presence, but Wallow gave them no chance to confront him as he washed and drowned them on the spot. With no more hindrances in his way, he entered the throne room and spotted two empty thrones.
“Ah, a lovely castle in a worthless world. Two thrones, eh? Well then...I guess the king will have to deal without his wife. Now where to find them?" Wallow said as he walked around.
It was like that for a while til he found a bedroom door. Suddenly when he approached it he turned into water and slunk underneath it. Inside the room was the bedroom of Shining Armor and Princess Cadence, the rulers of the Crystal Empire. The puddle of water started forming bigger and back into Wallow, as he loomed over the couple. The couple groaned, until their horns started glowing their their respective magical auras. The two suddenly woke up, “Cadence?” Shining Armor asked in concern.
“Shining Armor, what is...” they suddenly looked up and gasped seeing Wallow smirking evily at them.
"Hello there. I was hoping you would join us for a little wedding that Blackheart is planning. He's gonna marry Celestia once we have the contract of San Venganza. And I'm sure he would love to had you there." Wallow smirked.
"So this Blackheart was the one that caused this to happen!" Cadence shouted.
"Look I don't know who you are or how you got here but I'm warning you just this once. Get out of the Crystal Empire or face the consequences." Shining warned.
"Or what? You going to use that pathetic magic? Lemme show you mine." Wallow said.
So he conjured a huge ball of water and splashed it in Shining's face. He was all soaking wet but when he tried moving a demon merged out and dragged his body to the deep. He screamed and Cadence tried saving her husband but Wallow wouldn't let go.
"You ain't going nowhere. Now you are coming with me!" Wallow roared.
And so the two crashed through the window with Cadence screaming and Shining managed to break free from the water trap but he lost Wallow. Now he can only hope that Twilight and her friends will save both of them.
