Some magic should remain untouched.
While indentured to a harsh mistress, Crystalyn discovers her power over symbols and naively activates a curtain of darkness. Ever curious, her younger sister Jade touches the gateway and vanishes. Fearing for the safety of the sibling she'd always before kept from harm, Crystalyn jumps into a strange land infused with magic and those that Use. Aided by her own magic killing her with each use, she searches a realm locked in turmoil, her concern mounting. Dark and Light Users who manipulate the raw power of The Flow, seek to use her potent symbol magic for their own ends.
Half a world away, equipped with a seemingly useless ability to read auras, Jade embarks on a harrowing journey to escape the Dark Citadel with her life, and more importantly, her soul intact.
Escaping the immediate threat is not always the best plan, not when every dark thing on the world hunts you.
