From Introduction:
The Arena’s fighting pit has seen innumerable magical and engineered upgrades over its lifetime. The enchanted mechanisms in its walls and beneath the sand allow the Arena Master and his men to quickly, drastically alter the environment between rounds. These alterations begin with walls and inclines before other, more intricate mechanisms are attached. Some have the ability to spit fire, launch poisoned darts, or to trigger when a fighter strays too close. The randomness and unknowable dangers to every fight is one the Arena’s key draws, with audiences often cheering for or betting on the use of these traps to end a fight.
Erwin Redmane oversees the traps with the utmost detail and care. He does so with the assistance of both Eva Cinderbrow and Elias Gilderoy. The former has had a personal hand in advancing both the variety and functions of the traps, though often to the point of Redmane’s resistance. Opposite Cinderbrow is Marla Durand, who vocally opposes the lethality of the mechanisms.
