"I decided to float along the glacier's edge surveying its fissured surface."

The Icedart is a small, tundra-dwelling flyer from the tundra around Glacier Cap North on Darwin IV. It has a similar way of feeding on icebound algae as the icecrawler.

The icedart is a lighter-than-air-flyer that uses its hollow spikes to cling to the glacial ice during the fierce arctic storms. It is thought to get its nutrients from algae and microbes frozen in the ice, since it is never seen feeding on nearby tundra plants or other animals.
