Playing music was their forte. Amusing other people of their era with their fantastic pieces, they mesmerized almost everyone. They were beloved and treasured for their ingenious symphonies, and never seemed to disappoint.

Though, that all changed for them within the snap of a finger.

Wicked time travelers who are wanted by the supernatural law enforcement sneaked out of their imprisonment and planned something very dastardly. Something that would take the music world by storm. They had the most clever plan to kidnap loved musicians of old time periods and place them in a fantastical world known as the Bittersweet Ages.

In this age of time, there are extremely large and incredibly powerful beasts that lurk. Ones with fangs, claws, ugly faces and a thirst for blood. They disguise themselves in this beautiful environment with camouflage and strike when the time is right. Though, there are beasts that appear as themselves, yet are deadly. Like giant squirrels with pink fur that are hostile and cruel.

Yet, this world is very beautiful in scenery, with breath-taking waters, flower meadows, and very few buildings. Like a painting made with gorgeous colors, the air is clean and the sun shines brightly inside of a hue of blue. You can see the bottom of the rivers because of how pure the waters are. Rainbows paint the sky after gentle sprinkles of delightfully scented rain. There are small villages here and there with people, but that's about it with civilization. A little while back, humanity realized as a whole they were ruining the Earth. So, using their previous technology that they had, they restored the Earth bit by bit, and then once that was done, they trashed all of their technology and reverted back to the beauty of nature.
Though, there are flaws.
The flowers, even though they are beautiful, are artificial. Some of them may smell pleasant, but the aroma could poison one or knock them out. The rain might seem nice, but sometimes it burns the skin. It is a deadly paradise every now and then, and along with the beasts that lurk, they world may not seem the way it is. It does have its nice moments in the end. It's a much more beautiful world then it was not too long ago.

Even so, these musicians are trapped within a world that is not theirs. They all have amnesia except for the facts of:
They know that this world is not theirs after they wake up.
They still know how to play music, and they remember themselves.
They suddenly have a fighting style to protect themselves revolved around weapons and their music.

With the help of each other and some villagers with superpowers they meet along the way, they must find the answers of their amnesia to return to their time periods. Though, the time travelers won't let them escape their little game just yet.

"Music is mediator between spiritual and sensual life."
- Ludwig van Beethoven
