No one knows why Gaia's Ark came to Earth, but with it came the secrets of her runic cards.

Almost half a century has passed since prison ships enroute to Australia discovered the mysterious tower. Monarchies, republics, and trading giants came together to build a city around it, and contain the monsters spilling out of the rune-covered structure. The few that dared enter and climb it, learned the magic of Gaia's runic cards. Now, people delve into the tower's depths for fame and fortune or in search of power.

Diya Sen climbs the tower hoping to find clues regarding his missing brother and solve Gaia's mysteries. However, the warring noble houses stand in his way. Only allies and powerful cards will help him overcome obstacles and function outside the nobility's control. His mission won't be easy. Not all cards are made equal and sources of power are outside his—an ordinary man's—reach. If the direct approach won't help Diya achieve his goals perhaps the talents of a Spell Thief will.

This is a rewrite of The Pen Is Mightier. The magic system has been completely changed and the protagonist's fighting style/crafting and everything else is different as a result. There have also been major story point changes. The characters and settings are still mostly the same.
