Aquamare

As Night Glider sat around doing political stuff she was suddenly interrupted by a stallion running into the throne room in a panic

"Your highness we have a problem." he said

"What is it." Night Glider said

It's..." the stallion said

As he tried to finish his sentence a wired mysterious creature entered the throne room and knocked the gaurd out of the way with it's tail and approached Night Glider and said

"Hello Night Glider I'm Adagio Dazzle queen of the sirens and I'm here to give you a warning." she said

"What sort of warning?" Night Glider asked

"Either you give up your throne to me or you and your people will suffer my wrath ." Adagio said

"I will never bow to a creature like you." Night Glider said

"Then your people will suffer." Adagio said

As she headed towards the door Night Glider stood up and used her royal voice she said

"AS LONG AS I AM BREATHING YOU AND YOUR ARMY WILL NEVER TAKE MY KINGDOM!"

She than used her Triton and and aimed it at the siren and blasted her out of her kingdom

"General Davenport prepare your army to guard our kingdom 24 hours all day everyday." Night Glider said

"Yes, your highness ." Davenport said

After the attack  Night Glider and her general Davenport visit their historian Sheriff Silverstar

"What was that that attacked us in the throne room?" Night Glider asked

"It was a siren." Silverstar said

"What's a siren?" Davenport asked

"The sirens were beautiful but dangerous creatures who had the power to charm ponies with their music. But to maintain this power, they had to feed on the negativity and distrust of others. The more of this negative energy they consumed, the stronger their voices became, and the farther they could spread their dark magic." Silverstar said

"What happened to them?" Night Glider asked

"If the sirens had their way, they would have divided and conquered all of Equestria. But your father Star Swirl the Bearded wasn't having it. Rumor has it he found a way to banish them to another world – one where he believed their magic power would be lost." Silverstar said

"But three sirens manage to escape the attack and went into hiding."

"But that was ages ago. How come they're just surfacing' now?" Davenport asked

"I don't know. But if my hunch is right and it is the sirens who have come here to gain the throne, this is just the begining and I'm afrad that things are going to get worst." Silverstar said
