Meridian

Meridian is a comic by Cross Gen. It's set in a universe of flying ships and floating islands. The comic follows a noble girl named Sephie and her uncle Ilahn, both of whom receive mysterious Sigils at a reception on Meridian, the island that Sephie's father rules. Each Sigil seems to grant a different set of powers; Sephie focuses on healing and gentle pressure, while Ilahn uses his abilities for destruction and intimidation.

This series provides examples of:

 * Colour Coded for Your Convenience - The dark, brooding uncle's powers of destruction are red. The cheery and friendly girl's powers are yellow/gold.
 * Cool Airship - The flying airships that travel between islands count as this.
 * Fertile Feet - Sephie falls from a flying ship at high altitude and lands in a toxic wasteland, making a human-shaped crater around which plants start to grow.
 * Floating Continent - The wealthy in the world of Meridian live on floating continents to stay away from the polluted (Blighted) ground
 * Good Colors Evil Colors - See colour coded above
 * Grey Goo - The ground polution that causes ground structures to erode and fall apart quite quickly. All surface cities are continually being rebuilt.
 * A Million Is a Statistic - The girl's uncle sends an entire floating island to the ground, killing nearly everyone on board. Somehow it has less emotional impact then the death of the girl's parents.
 * Sky Pirates - Where there's flying airships, there's sky pirates
 * Steampunk - but only if you're wealthy enough to live on a floating island. Also some coalpunk for the super industrial island
