From the back cover:
The vast red desert domain of Arena sprawls south and westward from the nurturing plains of Penance. Spurred onward by the ancient promise of gold beneath the sands, massive armies of brutal warriors rumble across the scarred and wasted terrain. For the fortunate few, the ultimate dream of Arena still comes true--immeasurable riches, supreme command, and decades of extravagant and luxurious living atop the Queen's pedestal of pleasure. For most however, whatever dreams they may harbor are soundly crushed under years of backbreaking labor, constant battle, exhausting marches, gruesome butchery, and an infinity of accursed crimson sand. Oathbound: Arena provides a new entry point into the world of the Forge. This is the Domain of Barbello, the Mask of Fury, the invincible mistress of rage, pain, warfare, and death. Who amongst you can withstand her test?
