The Ortolan settlers on Hoth needed a renewable energy source to power their habitat in the Crescent Canyon Facility and help them expand their territory, so Ortolan engineers constructed a massive geothermal plant tapping directly into Hoth's underground volcano network. The Tromper Crags plant provided more than adequate power and heat to keep the Ortolans in relative comfort… until the White Maw came.
The pirate army's leaders understood the value of controlling the most abundant power resource on Hoth and quickly stormed the geothermal plant. Any Ortolans who did not immediately submit to White Maw authority were summarily executed. Now that the Republic and Empire have come to Hoth, the Tromper Crags facility has become hotly contested territory.
