The Silika were a sentient race native to the planet Dohu VII. A strict and unyielding honor code governed their society. Although they possessed three arms, their dexterity was limited by their short, thick fingers, and they also had short, squat legs. Their bodies were primarily composed of silicon, and mineral water, which they referred to as Silika water, acted as an intoxicant. It was common for Silika to engage in the Contest, a game centered around the consumption of water.
