Shadow Warrior saga

In the fog-enshrouded peaks of the island nation of Nehan, Ran, a newly minted shadow warrior is set loose on a musha shugyo, a wandering quest, whereby he must travel alone and hone his skills. Journeying aboard a merchant vessel, Ran hears tales of a mysterious lord believed to have the dead for his servants. Soon these tales prove all too real as Ran comes to the aid of Jysal, a beautiful sorceress, whose undeveloped power gives her the ability to heal a land - or destroy it.

When Ran, the Shadow Warrior, is dispatched to investigate rumors of an invasion massing to the north, he signs on as protection for a trade caravan. But once underway, the caravan is attacked by an overwhelming force of slavers who take Ran and several others captive. Dragged into the bowels of the earth as slave labor for a despot-in-exile eager to reclaim his throne, Ran must make a desperate escape with his friends if he has any hope of uncovering the truth about the invasion above ground.
