Descendants

Mal stared into her mother's eyes and chanted her spell. "The strength of evil is good as none when stands before four hearts as one. The strength of evil is good as none when stands before four hearts as one. The strength of evil is good as none when stands before four hearts as one."

Each time, her voice wavered a little more. Maleficent smiled, though it was hard to tell with her being a dragon. She kept mentally chanting her own spell against her daughter. The spell wasn't one of her normal spells – or, well, her old spells.

Suddenly, there was a flash and green smoke filled the room. Scared murmurs rippled through the unfrozen crowd. Though they were unfrozen, they didn't want to move for fear of Maleficent squashing or noticing them – you know, individually.

Ben stood with his parents, anxiously waiting for the smoke to clear so he could see what happened to Mal and her mother. If only the crowd's chattering were quieter, then he could hear Maleficent and Mal and the others. Then, he would know what was happening.

Slowly, the fog started to thin and he could make out more shapes. Evie, Carlos, and Jay stood, frozen, staring at a big lump on the ground. As the fog cleared even more, Ben realized two things – Mal was nowhere to be found and the lump was a sleeping dragon.

Percy Jackson

Five of the Seven were waiting in the War Room for Percy Jackson and Leo Valdez to show up. Jason Grace and Frank Zhang were having a small argument about the climbing wall. The girls were watching the boys and trying to guess who would win. Hazel Levesque was betting on Frank and Piper McLean, Jason. Annabeth Chase just found the argument amusing and wondered what Percy and Leo were doing.

A while and fifteen golden drachmas later, Percy walked in with Leo, Reyna, Nico di Angelo, and Will Solace. Everyone sat down, except Percy and Leo. They didn't have to tell everyone to be quiet because they already were. The looks on the eight people in front of them told Leo and Percy that they were expecting news of another war or some big enemy.

The two looked at each other and then back to the mini-crowd in front of them. Leo burst out laughing and Percy was soon to follow.

"You've got to stop being so serious!" Leo exclaimed.

Suddenly, Percy stopped laughing and said, "Leo, now's not the time, we have to leave in ten minutes. Guys, follow us, we have to be fast!"

Percy ran out the door and down the halls. It took a second before his words sank in and the others ran out behind him. Leo, knowing that that was going to happen, was close behind Percy and they were cackling like evil villains (yes that was in there intentionally). Nico was pissed that he couldn't shadow travel to wherever the Tartarus – I'm sorry, Erebus – Percy was taking them. His boyfriend, on the other hand, would have been a very angry son of Apollo had Nico shadow travelled.

They ended up in Bunker Nine in front of a ship that was just as big, if not bigger, than the Argo II. On its hull Olympia was painted in multiple colors, in multiple styles (I'll go into more detail in the A/N). Percy was hanging over the side, grinning at them.

"Climb on board, we've got….one minute until we have to leave!" another voice called over the edge.

"Travis! They aren't supposed to know we're on board until they get on board!" a third voice that was similar to the second chastised.

Looking at each other, the 'newcomers' boarded the Olympia. When they all boarded Annabeth said, "Why are we here, Seaweed Brain?"

Percy grinned. "Chiron said we can go on vacation, so, Leo and I built a ship!"

A/N: HI! I hope you liked this, tell me if you want me to continue this story. It's a crossover, so they will eventually meet. So, you probably all figured out what happened to Mal, but tell me what you think happened to her and why no one actually knows where she is.

This is one of the first descendants crossovers so, yay! R, R, F, & F.
