Development; plot; other tidbits

Hello, this is my Blog dedicated to a story that an idea popped up for.
It's about 5 friends who are very close to each other - however, a major cataclysm foretold their future - a future of emptiness, loneliness, and sadness. Along the way, they'll rediscover themselves, they'll look forward, think of the good and the bad, and they'll get through their journeys and be reunited once and for all
How the story will be set up:

Prologue
Part 1: Where the Autumn leaves fall
Part 2: Where the Ghosts haunt
Part 3: When Dawn rises
Part 4: When the Rose withers
Part 5: Where the Pixies sleep
End

Each part will hint the person that the adventure will follow next.

Part 1: Autumn Hex
A teenage girl who is lost in her thoughts and is going through frequent mental breakdowns. She finds a place where she regains her sense and breaks her breakdowns, then realizes her friends are gone, and she wants to know if the world will ever be the same again.

Part 2: Olivia GhostCatcher/DawnDust
A young girl who is extremely hyper and can't stand still for 10 seconds. However, after being separated from her love, she adventures out and a very awkward event takes place..

Part 3: Mark DawnDust
A teenage boy, who after losing his love, becomes very aware of the things around him, and suddenly realizes the world. He then ventures out to find the meaning of his life.

Part 4: Samantha RoseHeart
A teenage girl who has given up all hope in the world, and as she wakes up from the disaster, she notices a symbolic thing - one that has given her hope that her friends are still alive somewhere.

Part 5: Cheyenne PixiePetal
A teenage girl who has somehow landed in a foreign land, and she attempts to venture out of the land to find where she is. However, something bad will happen..will she be mistaken for what she is really not? Will she find her friends?

Also, take note that the parts all share the same time.

Prologue coming soon - when I'm not questing with Olivia, then I shall write the next part.
