Destiny Fulfiller. Chaos Project, #10

The war has finally arrived and Harmoni and her friends, allies and enemies have been flung far and wide across the storm ravaged realm. Just as they'd planned, Harm and her closest friends embark on their quests. They all have the same goal that will hopefully result in Order winning over Chaos. All four towers will need to be restored. Each one is guarded by a magical storm. Ice, lightning, wind and fire bar the crystal palace, sea castle, stone citadel and ebony fortress.
Alliances and unusual bonds will need to be formed in order for them to surmount their obstacles. Harm has been shown visions of what she and her friends need to do. She didn't realize she would be all alone. That doesn't last for long, but her companion is the last person she expected to be lumped with. Unfortunately, she isn't sure if she'll survive long enough to fulfil her destiny. Her illness is spreading far faster than she'd anticipated and she doesn't have a cure for it.
